Maximal Cohen-Macaulay modules over a noncommutative 2-dimensional singularity
Xiaoshan Qin, Yanhua Wang, James Zhang
We study properties of graded maximal Cohen-Macaulay modules over an N-graded locally finite, Auslander Gorenstein, and Cohen-Macaulay algebra of dimension two. As a consequence, w…

Noncommutative quasi-resolutions
X. -S. Qin, Y. -H. Wang, J. J. Zhang
The notion of a noncommutative quasi-resolution is introduced for a noncommutative noetherian algebra with singularities, even for a non-Cohen-Macaulay algebra. If A is a commutati…

Invariant theory for quantum Weyl algebras under finite group action
Secil Ceken, John H. Palmieri, Yanhua Wang +1
We study the invariant theory of a class of quantum Weyl algebras under group actions and prove that the fixed subrings are always Gorenstein. We also verify the Tits alternative f…
