Jeremy Booher


I am a postdoc in the Mathematics Department at the University of Arizona. I was a graduate student at Stanford University. My advisor was Brian Conrad. Here is my CV.

I am interested in algebraic number theory and arithmetic geometry, especially Galois representations and algebraic geometry in characteristic p.

My email is jeremybooher [AT] math.arizona.edu

My office is 315 in the math department.


Research

  • a-Numbers in Artin-Schreier Covers, with Bryden Cais, submitted. (MAGMA computations)
  • G-Valued Galois Deformation Rings when l ≠ p, with Stefan Patrikis, (to appear in MRL).
  • Minimally Ramified Deformations, (to appear in Compositio Mathematica).
  • Producing Geometric Deformations of Orthogonal and Symplectic Galois Representations, (to appear in The Journal of Number Theory).
  • Geometric Deformations of Orthogonal and Symplectic Galois Representations is the paper version of my thesis. It has been broken up into the two papers above for publication.
  • Evaluation of Cubic Twisted Kloosterman Sheaf Sums, an REU project with Anastassia Etropolski and Amanda Hittson. In International Journal of Number Theory, 6 (2010), pages 1349-1365.

  • Expository Notes and Articles

    Expository writing including my senior thesis, Part III essay, and notes for many of the talks I have given at PROMYS and in graduate school.

    Warning: the ones which came from the summers I spent as a counselor at PROMYS, use non-standard notation: taking a quotient of a ring by a principal ideal is denoted by a subscript. In particular, Zp is the integers modulo p, not the p-adic integers. Furthermore, the group of units in Zp is denoted by Up.


    Teaching

    Math 313 (Linear Algebra), two sections in Fall 2018.

    Math 432/532 (Topological Spaces), Spring 2018.

    Math 313 (Linear Algebra), two sections in Fall 2017.

    Math 446/546 (Theory of Numbers), Spring 2017.

    Math 129 (Calculus II), Spring 2017.

    Math 125 (Calculus I), Fall 2016.

    I was a graduate student TA at Stanford. During the summers, I worked at PROMYS (2007, 2008, 2010, 2011) and SUMAC (2013, 2014, 2015, 2016), and helped with SURIM (2012).

    Other Activities

    I am organizing the Algebra and Number Theory Seminar at the University of Arizona.

    I help with the Tucson Math Circle.
