Algebras graded by discrete Doi-Hopf data and the Drinfeld double of a Hopf group-coalgebra
Algebras discrete Doi-Hopf data the Drinfeld double
2010/11/9
We study Doi-Hopf data and Doi-Hopf modules for Hopf group-coalgebras. We introduce modules graded by a discrete Doi-Hopf datum; to a Doi-Hopf datum over a Hopf group coalgebra, we associate an algebr...
