Gauge Theory, Ramification, And The Geometric Langlands Program

TL;DR: In this paper, the authors show that the hypothesis of S-duality for surface operators leads to a natural extension of the geometric Langlands program for the case of tame ramification, which involves an action of the affine Weyl group on the cohomology of the moduli space of Higgs bundles with ramification.

Geometric construction of crystal bases

TL;DR: In this paper, the crystal associated to the quantized enveloping algebras with a symmetric generalized Cartan matrix was realized as a set of Lagrangian subvarieties of the cotangent bundle of the quiver variety, and a counterexample to the conjecture of Kazhdan--Lusztig on the irreducibility of the characteristic variety of the intersection cohomology sheaves associated with the Schubert cells of type A was given.

Representations of Coxeter Groups and Hecke Algebras.

TL;DR: In this article, the problem of decomposing this space of functions into irreducible representations of a finite Chevalley group G(Fq) is equivalent to decomposing the regular representation o f ~ | | (12) of a Coxeter group.
