Abstract:

The category of perverse sheaves on a complex variety is best understood via microlocal methods. Of particular interest is the compatibility with the vanishing cycles functor. It is natural to ask whether there is a similar viewpoint for perverse coherent sheaves on a scheme with a group action. I will give one answer to this question by taking local cohomology along "Lagrangian" subvarieties.
