Resolutions of Type Quantum Surface Singularities
Simon Crawford, Susan J. Sierra
Let be a Type quantum Kleinian singularity, which is an example of a noncommutative surface singularity. This singularity is known to ha…
Actions of Taft Algebras on Noetherian Down-Up Algebras
Simon Crawford, Jason Gaddis, Robert Won
We consider actions of Taft algebras on noetherian graded down-up algebras. We classify all such actions and determine properties of the corresponding invariant rings . We ide…
Group coactions on two-dimensional Artin-Schelter regular algebras
Simon Crawford
We describe all possible coactions of finite groups (equivalently, all group gradings) on two-dimensional Artin-Schelter regular algebras. We give necessary and sufficient conditio…
Chirality in 2d pAQFT
Sam Crawford, Kasia Rejzner, Benoit Vicedo
In this article, which builds upon the work done in our previous paper, the chiral aspects of 2dcft on globally hyperbolic Lorentzian manifolds are developed and explored within th…
Superpotentials and Quiver Algebras for Semisimple Hopf Actions
Simon Crawford
We consider the action of a semisimple Hopf algebra on an -Koszul Artin-Schelter regular algebra . Such an algebra is a derivation-quotient algebra for some twisted s…
Actions of Small Groups on Two-Dimensional Artin-Schelter Regular Algebras
Simon Crawford
In commutative invariant theory, a classical result due to Auslander says that if and is a finite subgroup of $\text{Aut}_{\text{gr}}(R) \cong \tex…
