Regularity and $\mathsf{K}_0$-Regularity under Finiteness Conditions

Abstract

The purpose of this work is to investigate various notions of regularity from the perspective of finiteness conditions, with the ultimate goal of identifying broad classes of rings that are $\mathsf{K}_0$-regular. In this direction, we revisit the classical concepts of coherence and von Neumann regularity, and establish new characterizations. We then focus on the study of \emph{$n$-coherent regular rings}, recently introduced in [31], and analyze their $\mathsf{K}$-theoretic behavior. Finally, we present applications illustrating how these approaches provide examples of $\mathsf{K}_0$-regular rings.
