Ting Xue: Character sheaves, Hecke algebras and Hessenberg varieties
28 September 2021 Abstract: We discuss character sheaves in the setting of graded Lie algebras. Via a nearby cycle construction irreducible representations of Hecke algebras of complex re ection groups at roots of unity enter the description of character sheaves. Recent work of Lusztig an

Ana Balibanu: The partial compactification of the universal centralizer
Abstract: Let G be a semisimple algebraic group of adjoint type. The universal centralizer is the family of centralizers in G of regular elements in Lie(G), parametrized by their conjugacy classes. It has a natural symplectic structure, obtained by Hamiltonian reduction from the cotangent
