广义P-平坦性和广义P-内射性的一些刻画
Some Characterizations on Generalized P-Flatness and P-Injectivity
摘要
Abstract
By means of homological algebra,some equivalent characterizations were given when R was left GP-injective ring,left GPP-ring or left GPF-ring.Having introduced the notions of GP-injective dimensions and GP-flat dimensions,we proved that left GP-injective global dimension is equal to right GP-weak dimension of R under the condition that R is left P-coherent.Furthermore,some newcharacterizations of GP-injective dimensions and GP-flat dimensions were also given.关键词
