Deformation cohomology for cyclic groups acting on polynomial rings
Colin M. Lawson, Anne V. Shepler
We examine the Hochschild cohomology governing graded deformations for finite cyclic groups acting on polynomial rings. We classify the infinitesimal graded deformations of the ske…

Graded deformations of skew group algebras for cyclic transvection groups acting on polynomial rings in positive characteristic
Lauren Grimley, Naomi Krawzik, Colin M. Lawson +1
We investigate deformations of skew group algebras that arise from a finite cyclic group acting on a polynomial ring in positive characteristic, where characteristic divides the or…
