Abstract
Spherical varieties form a remarkable class of algebraic varieties equipped with an action of a complex reductive group G. They include toric, flag and symmetric varieties. A natural invariant of an affine spherical variety X is the set S(X) of irreducible representations of G that occur in the coordinate ring O(X) of X. This talk will discuss the following question: given S(X), what are the possible multiplication laws on O(X)?
