Partial actions and cyclic Kummer's theory

Rings and Algebras 2020-04-29 v1

Abstract

We introduce a theory of cyclic Kummer extensions of commutative rings for partial Galois extensions of finite groups, extending some of the well-known results of the theory of Kummer extensions of commutative rings developed by A. Z. Borevich. In particular, we provide necessary and sufficient conditions to determine when a partial nn-kummerian extension is equivalent to either a radical or a II-radical extension, for some subgroup II of the cyclic group CnC_n.
