On the S-Krull dimension of a commutative ring
Abstract
We explore the concept of the S-Krull dimension in commutative rings, extending classical notions of Krull dimension by incorporating multiplicative subsets S of a ring R. We provide characterizations of S-prime, S-maximal, and S-minimal S-prime ideals, establishing foundational results crucial for understanding the S-Krull dimension. The paper also delves into properties of S-principal ideal S-domains, S-Artinian rings, and u-S-von Neumann regular rings, introducing an S-variant of the Division Algorithm. In the final section, the concept of S-height for S-prime ideals is defined, and the S-Krull dimension is analyzed through various characterizations and examples, with a particular focus on polynomial rings. We conclude with insights into the S-height of larger S-prime ideals of R[X] and their intersections with R, contributing to a deeper understanding of the S-Krull dimension.
