Abstract:
We slightly extend results of Evens and Mirković and “compute” the characteristic cycles of intersection cohomology sheaves on transversal slices in a double affine Grassmannian. We propose a conjecture relating the hyperbolic stalks
and microlocalization at a torus-fixed point in a Poisson variety.
The research of M. F. was carried out at the IITP RAS at the expense of the Russian Science Foundation (project no. 14-50-00150). The article was prepared by D. K. within the framework of a subsidy granted to the Higher School of Economics by the Government of the Russian Federation for the implementation of the Global Competitiveness Program.
