Hopf algebra actions on differential graded algebras and applications
arXiv:1007.4983
Abstract
Let be a finite dimensional semisimple Hopf algebra, a differential graded (dg for short) -module algebra. Then the smash product algebra is a dg algebra. For any dg -module , there is a quasi-isomorphism of dg algebras: $\mathrm{RHom}_A(M,M)\#H\longrightarrow \mathrm{RHom}_{A\#H}(M\ot H,M\ot H)$. This result is applied to -Koszul algebras, Calabi-Yau algebras and AS-Gorenstein dg algebras
