"Nonarchimedean integration over spherical varieties"


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.
