Quantum toric degeneration of quantum flag and Schubert varieties
Laurent Rigal, Pablo Zadunaisky
We show that certain homological regularity properties of graded connected algebras, such as being AS-Gorenstein or AS-Cohen-Macaulay, can be tested by passing to associated graded…

Twisted semigroup algebras
Laurent Rigal, Pablo Zadunaisky
We study 2-cocycle twists, or equivalently Zhang twists, of semigroup algebras over a field k. If the underlying semigroup is affine, that is abelian, cancellative and finitely gen…

Quantum analogues of Richardson varieties in the grassmannian and their toric degeneration
Laurent Rigal, Pablo Zadunaisky
In the present paper, we are interested in natural quantum analogues of Richardson varieties in the type A grassmannians. To be more precise, the objects that we investigate are qu…
