Classification, Koszulity and Artin-Schelter Regularity of certain Graded Twisted Tensor Products

Andrew Conner, Peter Goetz

Let $\mathbb{k}$ be an algebraically closed field. We classify all of the quadratic twisted tensor products $A{\otimes }_{\tau }B$ in the cases where $(A, B) = (\mathbb{k}[x], \mathbb{k}[…
