Abstract:
When the group, or the isotropy subgroup, is non-compact, classical Crofton type formulae may fail to exist because of the appearence of divergent integrals. The aim of the talk is to show that in some situations this problem may be circumvented replacing the invariant measure by an invariant distribution. The procedure will be illustrated by basic examples and applications in convex geometry.
