"Nonarchimedean integration over spherical varieties"
Abstract
Spherical varieties are equivariant compactifications of spherical homogeneous
spaces. According to Luna and Vust, one can describe a spherical embeddings of a given
spherical homogeneous space by some combinatorial data consisting of colored
cones. The purpose of the talk is to explain how the nonarchimedean integration
allows to compute the Betti numbers of smooth projective spherical varieties.
