Examples of polynomial identities distinguishing the Galois objects over finite-dimensional Hopf algebras
Christian Kassel
We define polynomial H-identities for comodule algebras over a Hopf algebra H and establish general properties for the corresponding T-ideals. In the case H is a Taft algebra or th…

Norm formulas for finite groups and induction from elementary abelian subgroups
Eli Aljadeff, Christian Kassel
It is known that the norm map N_G for a finite group G acting on a ring R is surjective if and only if for every elementary abelian subgroup E of G the norm map N_E for E is surjec…

Explicit elements of norm one for cyclic groups
Eli Aljadeff, Christian Kassel
Let G be a cyclic p-group of order p^n acting by automorphisms on a (non-necessarily commutative) ring R. Suppose there is an element x in R such that (1 + t + ... + t^{p-1})(x) =…
