Title: Acyclicity of gamma sheaves
Abstract: A gamma sheaf is a certain ladic sheaf on a reductive group defined over a finite field which generalizes the classical ArtinSchreier sheaf. In my talk I will explain the motivation and the proof of the acyclicity of such gamma sheaves for general linear groups. This result is originally conjectured by BravermanKazhdan, the proof is joint work with B. C. Ngo.
