On the separability of the restriction functor
Let G be a group, Λ = L σ∈G Λσ a strongly graded ring by G, H a subgroup of G and ΛH = L σ∈H Λσ. We give a necessary and sufficient condition for the ring Λ/ΛH to be separable, generalizing the corresponding result for the ring extension Λ/Λ1. As a consequence of this result we give a conditio...

| description |
Let G be a group, Λ = L
σ∈G Λσ a strongly
graded ring by G, H a subgroup of G and ΛH =
L
σ∈H Λσ. We
give a necessary and sufficient condition for the ring Λ/ΛH to be
separable, generalizing the corresponding result for the ring extension Λ/Λ1. As a consequence of this result we give a condition for
Λ to be a hereditary order in case Λ is a strongly graded by finite
group R-order in a separable K-algebra, for R a Dedekind domain
with quotient field K.
