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

Andrew Conner, Peter Goetz

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

Noncommutative Knörrer periodicity and noncommutative Kleinian singularities

Andrew Conner, Ellen Kirkman, W. Frank Moore +1

We establish a version of Knörrer's Periodicity Theorem in the context of noncommutative invariant theory. Namely, let $A$ be a left noetherian AS-regular algebra, let $f$ be a nor…

Finiteness conditions on the Yoneda algebra of a monomial algebra

Andrew Conner, Ellen Kirkman, James Kuzmanovich +1

Let A be a connected graded noncommutative monomial algebra. We associate to A a finite graph Γ(A) called the CPS graph of A. Finiteness properties of the Yoneda algebra Ext_A(k,k)…
