Generalized characters for glider representations of groups
Frederik Caenepeel, Fred Van Oystaeyen
Glider representations can be defined for a finite algebra filtration FKG determined by a chain of subgroups 1 < G_1 < ... < G_d = G. In this paper we develop the generalized chara…
Glider representations of group algebra filtrations of nilpotent groups
Frederik Caenepeel, Fred Van Oystaeyen
We continue the study of glider representations of finite groups with given structure chain of subgroups . We give a characterizat…
Clifford theory for glider representations
Frederik Caenepeel, Fred Van Oystaeyen
Classical Clifford theory studies the decomposition of simple -modules into simple -modules for some normal subgroup . In this paper we deal with chains of…
Localization and sheaves of glider representations
Frederik Caenepeel, Fred Van Oystaeyen
The notion of a glider representation of a chain of normal subgroups of a group is defined by a new structure, i.e. a fragment for a suitable filtration on the group ring. This is…
Hopf dense Galois extensions with applications
J. He, F. Van Oystaeyen, Y. Zhang
Let be a finite dimensional Hopf algebra, and let be a left -module algebra. Motivated by the study of the isolated singularities of and the endomorphism ring $\ma…
Twisted algebras and Rota-Baxter type operators
Florin Panaite, Freddy Van Oystaeyen
We define the concept of weak pseudotwistor for an algebra in a monoidal category , as a morphism in , satis…
