On the Betti numbers of Springer fibers for classical types

Abstract

For a Weyl group WW of classical type, we present a formula to calculate the restriction of (graded) Springer representations of WW to a maximal parabolic subgroup WW' where the types of WW and WW' are in the same series. As a result, we obtain recursive formulas for the Betti numbers of Springer fibers for classical types.
