About this event
Guy Shtotland from Ben-Gurion University discusses the Kazhdan–Lusztig isomorphism. He explains how this mathematical relationship applies to spherical varieties like GL2n\Sp2n. The talk explores connections between affine Hecke algebras and equivariant K-theory.

Speaker: Guy Shtotland (Ben-Gurion University) Title: Relative Kazhdan Lusztig isomorphism for GL2n\Sp2n Abstract: The Kazhdan–Lusztig isomorphism, which relates the affine Hecke algebra of a p-adic group to the equivariant K-theory of the Steinberg variety of its Langlands dual, played a key role in the proof of the Deligne–Langlands conjecture on the classification of tamely ramified irreducible representations. For a spherical variety X, we can construct two modules over the affine Hecke algebra: the first by considering Iwahori invariant functions on X, and the second using relative Langlands duality and equivariant K-theory. It is natural to expect a relationship between these modules. I will discuss this relationship for X = GL2n\Sp2n and its application to the study of distinguished representations.
