Singular Supports for Character Sheaves on a Group Compactification
Let G be a semisimple adjoint group over C and Ḡ be the De Concini-Procesi completion of G. In this paper, we define a Lagrangian subvariety Λ of the cotangent bundle of Ḡ such that the singular support of any character sheaf on Ḡ is contained in Λ.
