Root subgroups on affine spherical varieties

Ivan Arzhantsev, Roman Avdeev

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…

On extended weight monoids of spherical homogeneous spaces

Roman Avdeev

Given a connected reductive complex algebraic group $G$ and a spherical subgroup $H \subset G$ , the extended weight monoid $Λ_{G}^{+} (G / H)$ encodes the $G$ -module structures o…
