The Demazure roots of a spherical embedding

This talk is devoted to the classification of normalized additive group actions on affine spherical varieties. After recalling some basic notions concerning the Luna-Vust theory, we will present a description of these actions which generalizes the classical toric case.
Joint work with Alexander Perepechko.
