Object-unital groupoid graded rings, crossed products and separability
J Cala, P Lundström, H Pinedo - Communications in Algebra, 2021 - Taylor & Francis
We extend the classical construction by Noether of crossed product algebras, defined by
finite Galois field extensions, to cover the case of separable (but not necessarily finite or …
