  19. Extensions of loop groups, H^4(BK,Z), and reciprocity, preprint

    20. Abstract: Given a compact Lie group K, we classify the Aut(P)-invariant central extensions of the gauge group K(P), for each K-bundle P\toS^1. Given a level l\inH^4(BK,Z), we associate a central extension to each K(P) such that this family of extensions has a reciprocity property introduced by G Segal [Note: This paper is 15 years in development, and over 100 pages. It is a step in a larger project to address a conjecture of physicists, e.g. Moore and Seiberg, concerning the classification of rational conformal field theories]

    27. Abstract: In this paper we introduce a framework for harmonic analysis associated to infinite dimensional Riemannian symmetric spaces of classical type, involving the notion of a rigged manifold. We prove the existence (and in some cases uniqueness) of invariant measures associated to riggings of infinite dimensional classical symmetric spaces. The associated L^2 representations decompose uniquely as direct integrals of irreducible spherical representations [The Plancherel formula has been found by Borodin and Olshanskii].
