Equivalences of (co)module algebra structures over Hopf algebras
Ana Agore, Alexey Gordienko, Joost Vercruysse
We introduce the notion of support equivalence for (co)module algebras (over Hopf algebras), which generalizes in a natural way (weak) equivalence of gradings. We show that for eac…

Categories and weak equivalences of graded algebras
Alexey Gordienko, Ofir Schnabel
When one studies the structure (e.g. graded ideals, graded subspaces, radicals, ...) or graded polynomial identities of graded algebras, the grading group itself does not play an i…
