Comultiplicative map on projective resolution for a family of algebras one of which is cluster-tilted type D4
Pratyush Mishra, Tolulope Oke
We construct a comultiplicative map on the projective bimodule resolution for a family of algebras one of which is cluster-tilted of type D4. The comultiplicative map is presented…

Gerstenhaber brackets on Hochschild cohomology of general twisted tensor products
Tekin Karadag, Dustin McPhate, Pablo S. Ocal +2
We present techniques for computing Gerstenhaber brackets on Hochschild cohomology of general twisted tensor product algebras. These techniques involve twisted tensor product resol…

Actions of Drinfeld doubles of finite groups on Artin-Schelter regular algebras
Ellen Kirkman, W. Frank Moore, Tolulope Oke
For a finite group and an algebraically closed field of characteristic zero we consider Artin-Schelter regular algebras on which the Drinfeld double acts inn…
