1997-05-01: Lyn Reid receives $50 for decoding message..

The Message has been Decoded! David Lovelock and Bill Velez received the following message from Lyn Reid. She was the first to break our message and we have gladly paid her the $50. It is clear that David Lovelock composed the message!

Date: Thu, 01 May 1997 23:15:58 -0700 
To: velez@math.arizona.edu 
From: Lyn R Reid 

I brought the Enigma program home to give it a shot tonight. In under an hour of playing with the program, I decoded the message. 

On the settings for day 117, I noticed that the first six characters read "ZULZUL". Remembering the additional trick you said the Germans used, I decided to change my rotor settings to Z, U, L. After doing that, I decoded the message "David is handsome, intelligent, and modest. Bill is not." (The spacing and punctuation I added, obviously). 

For reference, the settings for day 117 were: 

Rotors V, I, IV 
Init settings R, E, D 
Plugboard C-G, H-I, M-O

2005-12-06: New milestone for undergraduate program.Greg Farneth is the first student to be the 450th math major. In honor of the occasion, alumna Dr. Abbie Warrick presented Greg with a book about the history of mathematics (see photo below). This is especially fitting in light of Dr. Warrick’s long history with the University of Arizona Mathematics Department, having received three degrees with us (and one in electrical engineering). Her undergraduate degree in Engineering Mathematics was received in 1989. She received MS degrees in Applied Mathematics and Electrical Engineering in 1991 and 1993, respectively, and a PhD in Applied Mathematics in 1996. She has been employed by the Lawrence Livermore National Laboratory (LLNL) as an electrical engineer since completing the PhD in 1996. She returns frequently to the University of Arizona to recruit UA students for permanent and internship positions at LLNL. Greg Farneth is a new transfer student to the University of Arizona this semester, majoring in Mathematics and Molecular and Cellular Biology. He is considering combining these interests for a career in epidemiology.

2009-03-29: 2008 William Lowell Putnam Competition Results.

The Department of Mathematics would like to congratulate the University of Arizona team—Sean Howe, Kyle Marshall, and Derrick Sund—on the team's 31st ranking among over 1600 competing teams in the William Lowell Putnam Competition. Individually, Derrick Sund placed in the top 200 and Sean Howe placed in the top 500, both for the second year in a row.

The Putnam competition is constructed to test originality as well as technical competence. Contestants are expected to be familiar with the formal theories embodied in undergraduate mathematics. It is also expected that questions involving elementary concepts from group theory, set theory, graph theory, lattice theory, number theory, and cardinal arithmetic will not be entirely foreign to the contestants. In addition, questions may be included that cut across the bounds of various disciplines, and questions may be included that do not fit into any of the usual categories.

The examination is held on the first Saturday of December and consists of two periods of exactly three hours each with a two-hour break between the two sessions, under the official supervision of a faculty member, in our case, David Savitt.

2009-04-13: Yijun Shao is Recipient of Daniel Bartlett Memorial Fellowship.

We are pleased to announce that Yijun Shao has been selected to receive the Daniel Bartlett Memorial Fellowship for summer 2009. Several very strong candidates were nominated and selecting just one was not easy. Yijun's outstanding research in a difficult area of geometry makes him a very deserving recipient of this award.

Yijun entered the PhD program in Mathematics in August 2004, passed his qualifying exams in August 2005, and his comprehensive exam in Spring 2007. He is working on his dissertation research with Prof. Yi Hu. His joint work with his advisor on the moduli space of algebraic maps from the projective line to a projective space has already been submitted for publication. He is now working on vastly generalizing this work to moduli spaces of maps to all homogeneous spaces, in particular to the Grassmannians.

In addition to teaching a variety of courses, Yijun has also served as a super-TA for Introduction to Proofs, Principles of Analysis, and Lie Groups and Lie Algebras.

Yijun entered the graduate program one year after Daniel Bartlett. He took several courses with Daniel and remembers him as being "really smart" and able to absorb new material very quickly.

This summer, Yijun will concentrate on his dissertation research. He expects to finish his PhD next year. Please join me in congratulating him on his accomplishments to date and wishing him the best for the future.

2009-06-01: NSF Grant awarded to Romyar Sharifi for Iwasawa Theory and Galois Representations research project.The project involves a study of operations in the Galois cohomology of number fields and their application in Iwasawa theory. The PI has conjectured an explicit relationship between the values of a cup product on cyclotomic p-units and p-adic L-values, taken modulo p, of newforms that satisfy congruences with Eisenstein series at a prime above p. The proposed research relates to this through a number of distinct but intertwined sub-projects, including an algebraic study of the structure of the Selmer groups of the associated modular representations, the exploration of relationships with Kato's Euler system and classical main conjectures, and the precise formulation of certain generalizations. A remarkable aspect of algebraic number theory lies in the connections it finds between objects that appear to be of entirely different natures. These objects can roughly be described as falling into two classes: those that are algebraic, and those that are analytic. The algebraic objects are typically found by considering numbers that can be formed by applying the standard operations of arithmetic to the roots of polynomial equations, or by considering the symmetries of those roots. The analytic objects are often functions on interesting spaces with values that are complex numbers. The project concerns an unexpected direct comparison between the algebraic values of a function on pairs of numbers and the analytic power series attached to highly symmetrical complex-valued functions known as modular forms. The PI is exploring this and its many consequences in arithmetic.

2009-06-03: Yi Hu Funded by NSF for Projects on Modular Algebraic Geometry.. Continuing his previous work on elliptic stable maps, the PI's near-term objective is to complete his joint work on the structures of the moduli spaces of genus-two stable maps; then strengthen the results that they already obtained in high-genus cases; for any genus, they recently obtained the enumerative invariants using derived resolutions over the primary components of the moduli spaces of stable maps; these new invariants were then used to formulate a precise recursive relation for high-genus GW invariants of smooth quintic; these should be useful for verifying physicists' high-genus Mirror Symmetry prediction. Further, the PI plans to push and apply the techniques that they have developed to Gromov-Witten theory, to Mirror Symmetry, and possibly also to birational geometry. In addition to the above, the PI has introduced a modular compactification of the space of n points in general linear position on the projective plane; this potentially has significant consequences on singularity theory. Lastly, he is also working toward the weighted strong factorization for projective varieties with at worst finite quotient singularities through GIT approach.

2009-06-23: Pham Huu Tiep's project "Group Representations and Applications" has been recently funded by the NSF.. This proposal focuses on several important problems in representation theory of finite groups and its applications. It ties together different areas of mathematics, such as finite groups and algebraic groups, finite permutation group theory, group cohomology, combinatorics and finite geometry, algebraic geometry, and string theory, with the main unifying ingredient being the representation theory. Many of the problems addressed in the proposal come up naturally – some long-standing and play a central role – in the group representation theory, and others are motivated by various important applications.
2009-06-23: David Savitt is funded by the NSF for p-ADIC AND MOD p GALOIS REPRESENTATIONS..The PI’s research areas are number theory and representation theory. In particular, the PI studies p-adic Galois representations and p-adic Hodge theory, with an eye towards applications to the modularity of Galois representations and the Langlands program. Following the recent proof of the Fontaine-Mazur conjecture for GL2 (Q), attention to groups other than GL2 and fields other than Q has intensified. The PI proposes a number of projects that will contribute significantly to this effort, organized around the theme of p-adic representations and their reduction modulo p. The PI will study the weight in Serre’s conjecture for arbitrary split reductive groups and arbitrary number fields, with the goal of giving an explicit Serre weight recipe in considerable generality. The PI will produce evidence for generalizations of the Breuil-M ́zard conjecture in both qualitative and quanetitative forms, and will prove some cases of such a generalization, yielding applications to modularity. A third component of the project involves the explicit reduction modulo p of p-adic Galois representations, again with applications to the Langlands program.

2009-08-18: Cushing Funded for study of The Dynamics and Evolution of Semelparity. Intellectual merits. Biological semelparity is a life history adaptation in which an individual organism reproduces once and then, or shortly thereafter, dies. This reproductive strategy is found throughout the plant and animal kingdoms. The trade-offs between reproduction and survival and the distinctions between semelparous and iteroparous life cycles have long been recognized as key issues involved in the study of life history strategies. Major topics of interest are (1) the population dynamic consequences and (2) the evolutionary advantage or disadvantage of semelparity (versus iteroparity). Recent developments in the modeling of semelparity, using methods of nonlinear dynamics and bifurcation theory, have established a fundamental dynamic dichotomy that is of both biological and mathematical interest. From a mathematical point of view, models for the dynamics of semelparous species lie outside the standard theory of general structured population dynamics in that the primary bifurcation from extinction to persistence that occurs at R0 = 1 is of high codimension. The challenge of determining the dynamic consequences of this fact have been met only in the low dimensional cases (shorter maturation periods), and even then not thoroughly. These preliminary results establish a dynamic dichotomy for semelparous species that consists, roughly speaking, of an alternative between equilibration with overlapping generations or oscillations (not necessarily periodic) with non-overlapping generations. The nature of the oscillations in the later case, however, are not well understood, except in the lowest dimensional cases which show that they can be complex. The first goal of the proposed research is to carry out a mathematical study of this dynamic dichotomy that will clarify the nature of these oscillations. The methods will involve stability analysis, bifurcation methods, perturbation expansions, monotone semi-flow theory, the use average Lyapunov functions, persistence theory, and numerical simulations. The second goal of the proposed research is to address questions about the evolution of semelparity and the possibility of its being an ESS (evolutionary stable strategy). The method to be used is Darwinian dynamics (based on evolutionary game theory), a methodology that extends a population dynamic model to include the dynamics of an evolving (mean phenotypic) trait which in turn affects the population dynamics (through its influence on birth and death rates). Using biologically reasonable trade- offs to build sub-models for fecundity and survivorships as functions of an evolving trait, we will study the circumstances under which semelparity is evolutionarily favored and when it is not. The Darwinian dynamics approach allows the methods of nonlinear dynamics and bifurcation theory to be applied to these evolutionary questions. Broader impacts. The investigation of many problems in the biosciences is based on population dynamics, including problems concerning the spread of diseases, invasion of non-native species, the stability and diversity of ecosystems, endangered species, the management of agricultural systems, the operation of fisheries, and the design of nature preserves. The life history strategy of a species is, in turn, fundamental to understanding its population dynamics. A thorough understanding of the dynamics and evolution of semelparous (and iteroparous) species promotes a deeper understanding of those disciplines built on and related to population dynamics. Furthermore, the development of a modeling methodology for studying the dynamics and evolution of semelparous species allows for the construction of more accurate models for applications to specific species. For example, many diseases are spread by semelparous organisms, many parasites are semelparous, and many plants of agriculture importance are semelparous. The dynamic models to be used in this research are of types (difference equations) that are particularly accessible to those (including undergraduates) with a limited background in dynamical systems. Because of the quick learning curve for becoming adept at using these kinds of models, the proposed research provides abundant research opportunities for undergraduates and graduates that introduces them, an accessible context, to sophisticated concepts and methods in the theory of dynamical systems and permits them to make interesting applications that make solid contributions to biological problems.

2009-08-27: *You like our 'gem?' We'll trade you * Re: the Aug. 21Arizona Daily Star article "'Modern' gems are cited.".I think I speak on behalf of everyone in the department when I say that we were honored to have our building recognized as a gem. So honored, in fact, that we would be delighted to trade it with anybody who truly appreciates it. In addition to its architectural distinction, the building solves an interesting mathematical problem: how to provide the least space for the largest footprint. I'm sure that one day we will miss its sloping floors, disintegrating walls and cranky elevator. But that day, long awaited, has not yet come. /William McCallum / /Chair, UA Department of Mathematics, Tucson /

2009-09-16: Alan Newell has received funding for his grant entitled "Patterns in Nature and in the Laboratory.". Patterns of an almost periodic nature are to be found almost everywhere in nature and are the subject of many laboratory experiments. Open any journal these days in Physics, Biology, Chemistry, Optics and Geophysics and one will find articles on some remarkable aspect and utility of self-organizing patterns. One area of much current interest, especially given the new NSF supported iPlant consortium, has been the grand challenge of understanding how biological systems evolve and self organize. One of the new foci of interest is also one of the oldest, the appearance of organized patterns and configurations on the surfaces of plants near the shoot apical meristem. New experiments on the important role of auxin, many on the plant Arabidopsis, suggest that biochemical processes are involved in initiating the observed phyllotactic patterns. The PI, who has forty years experience in the field, and his former and current graduate students Patrick Shipman and Zhiying Sun (supported by NSF grant DMS 0501243), have built models involving both biochemical and mechanical processes which are inspired and informed by the experiments of Kuhlmeier et. al. and Meyerowitz et. al. which appear to give results in close harmony with observations. The proposal also addresses properties of patterns far from onset; gradient-like behaviors, condensation of the Gaussian curvature of the phase function and a remarkable correspondence between three dimensional line singularity loops and quarks and leptons.

2009-11-19: Shankar Venkataramani funded by US Israel Foundation for his proposal: EXPERIMENTAL AND THEORETICAL STUDY OF ACTIVELY DEFORMING SHEETS.Abstract Many natural structures are made of soft tissue that undergoes complicated continuous shape transformations that accurately and reliably serve specific elaborate tasks. Such processes can be slow, as in growth of a tissue, or rapid and be used for the production of mechanical work, as in the case of the action of the hart. In contrast, most man made "machines" are based on translation or rotation of rigid "driving" components that , in some cases, deform passive soft components. One can see the potential in mimicking natural shaping mechanisms with artificial materials. However, our ability to produce controlled motions of soft tissue is poor. The difficulties in controlling this type of shaping involve mathematical and experimental problems. Problems such as definitions of strains in evolving bodies, designe of responsive materials and understanding the underlying mechanical instabilities are of central importance. We propose a research that will join our expertise in mathematics, mechanics, experimental physics and chemical engineering (Ron correct), that will be focused on studying the principles of shaping via active growth and will take the first steps in implementing them. The work will consist of intensive interaction between theoretical and experimental work.

Jakobsen will be here for research collaboration with ACMS, which has expertise in computational electromagnetics and optics. Jakobsen is a former doctoral student at the UA and his research interests are in: The calculation of classical and quantum electrodynamically induced forces on wavelength sized objects in the linear response regime is a mathematically challenging problem of considerable technological interest. In this size regime the dipole and geometric optics approximations breaks down and the goal is to develop effective computational methods. For classically induced forces I am using a reformulation of the Maxwell equations in terms of a set of singular boundary integral equation. The challenge is to solve these integral equations effectively for complex geometries and material properties. For quantum electrodynamically induced forces(Casimir forces) the mathematical object of interest is the Feynman propagator. Because of the usual ultraviolet divergences of quantum fields, no boundary integral formulation for the propagator is known. My current research activity in this area is aimed at finding a boundary integral formulation for the electromagnetic Feynman propagator with the ultimate goal of developing an effective computational approach for the computation of Casimir forces.
