仿射Hecke代数的两种几何实现

On two geometric realizations of an affine Hecke algebra

Roman Bezrukavnikov

摘要:

这篇文章是对局部几何朗兰兹对应理论的贡献。其主要结果是一个范畴的同构之间的(扩展)仿射Hecke代数,被认为是局部非阿基米德域上的半单群上的Iwahori双不变函数的代数,以及Langlands对偶群的Steinberg簇上的等变相干层的Grothendieck群;由于Kazhdan-Lusztig和Ginzburg的同构是证明局部Langlands代数的一个关键步骤。本文是与S. Arkhipov,它依赖于与Z.云

英文摘要:

The article is a contribution to the local theory of geometric Langlands correspondence. The main result is a categorification of the isomorphism between the (extended) affine Hecke algebra, thought of as an algebra of Iwahori bi-invariant functions on a semi-simple group over a local non-Archimedian field, and Grothendieck group of equivariant coherent sheaves on Steinberg variety of the Langlands dual group; this isomorphism due to Kazhdan--Lusztig and Ginzburg is a key step in the proof of tamely ramified local Langlands conjectures. The paper is a continuation of an earlier joint work with S. Arkhipov, it relies on technical material developed in a paper with Z. Yun.
