On orbits of the automorphism group of toroidal spherical varieties
Alexander Chernov, Klim Rolgin
In this paper we study the orbits of the automorphism group on a toroidal spherical variety. In the affine case, we prove that two points lie in the same orbit of the identity comp…
Monomial algebras and -equivariant embeddings into toric varieties
Alexander Chernov
An induced additive action on a projective variety is a regular action of the group on with an open orbit that can be extended to a re…
On the generators of coordinate algebras of affine ind-varieties
Alexander Chernov
In this paper we study the structure of the coordinate ring of an affine ind-variety. We prove that any coordinate ring of an affine ind-variety which is not isomorphic to an affin…
Additive actions on projective hypersurfaces with a finite number of orbits
Viktoriia Borovik, Alexander Chernov, Anton Shafarevich
An induced additive action on a projective variety is a regular action of the group on with an open orbit, which can be extended to…
