Let G be a connected reductive algebraic group over the field of complex numbers and let G/H be
a spherical homogeneous space. A Gequivariant open embedding of G/H into an irreducible normal
variety X is called a spherical embedding.
Using the combinatorial invariants of G/H from the previous talk, a spherical embedding G/H > X
can be combinatorially described by its colored fan, which contains a colored cone for each
Gorbit in X.
In the special case of toric varieties, we recover the more widely known description of toric
varieties in terms of cones and fans.
This talk contains no new results and is based on Friedrich Knop's paper with the same title.
