Regular parameter elements and regular local hyperrings

Abstract

Inspired by the concept of regular local rings in classical algebra, in this article we ini-tiate the study of the regular parameter elements in a commutative local Noetherian hyperring. These elements provide a deep connection between the dimension of the hyperring and its primary hyperideals. Then, our study focusses on the concept of regular local hyperring R, with maximal hyperideal M, having the property that the dimension of R is equal to the dimension of the vectorial hyperspaceM over the hyperfieldRM2 M. Finally, using the regular local hyperrings, we determine the dimension of the hyperrings of fractions.
