Invariant theory for coincidental complex reflection groups
Victor Reiner, Anne V. Shepler, Eric Sommers
V.F. Molchanov considered the Hilbert series for the space of invariant skew-symmetric tensors and dual tensors with polynomial coefficients under the action of a real reflection g…
Invariants of polynomials mod Frobenius powers
C. Drescher, A. V. Shepler
Lewis, Reiner, and Stanton conjectured a Hilbert seriesfor a space of invariants under an action of finite general linear groups using -binomial coefficients. This work give…
Gerstenhaber brackets for skew group algebras in positive characteristic
A. V. Shepler, S. Witherspoon
The deformation theory of an algebra is controlled by the Gerstenhaber bracket, a Lie bracket on Hochschild cohomology. We develop techniques for evaluating Gerstenhaber brackets o…
Group-twisted Alexander-Whitney and Eilenberg-Zilber maps
A. V. Shepler, S. Witherspoon
We define group-twisted Alexander-Whitney and Eilenberg-Zilber maps for converting between bimodule resolutions of skew group algebras. These algebras are the natural semidirect pr…
