Characterizing Regular Local Rings via Analogues of (*)-properties

Abstract

Let $R$ be a commutative noetherian local ring. As analogues of $(\ast )$-properties introduced by Ghosh, Gupta, and Puthenpurakal, we introduce and study $(\mathrm{A})$-properties, $(\mathrm{B})$-properties, and $(\mathrm{C})$-relations. Using these three notions, we establish a criterion for a local ring to be regular. This recovers and refines the main result of Ghosh, Gupta, and Puthenpurakal and has further applications.
