Informal Friday Seminar: Maltoni -- Affine Hecke algebras and equivariant K-theory

This talk is the continuation of the preceding IFS by Gaston.  We have been introduced
to the Bernstein presentation of the affine Hecke algebra and a theorem has been
announced providing an isomorphism of this algebra with the equivariant K-theory of the
Steinberg variety with respect to the GxC*-action.  I will start by a brief introduction
to equivariant K-theory and recall the definition of the Steinberg variety in order to
make this statement precise.  The second part of the talk will be devoted to
understanding this isomorphism in the case of SL2.
