Root subgroups on affine spherical varieties

Given a connected reductive algebraic group \(G\) and a Borel subgroup \(B \subseteq G\), we study \(B\)-normalized one-parameter additive group actions on affine spherical \(G\)-varieties. We establish basic properties of such actions and their weights and discuss many examples exhibiting various f...
