Twisted Semigroup Algebras

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 generated, then Spec K[S] is an affine toric variety over K, and we refer to the twists of K[S] as quantum affine toric var...
