复形的 Cartan-Eilenberg Gorenstein 投射维数
Cartan-Eilenberg Gorenstein projective dimension of complexes
摘要
Abstract
After introducing the concept of Cartan‐Eilenberg (CE ) Gorenstein syzygy complexes , it is proved that a complex K is CE Gorenstein n‐syzygy complex if and only if it is a CE n‐syzygy complex for any positive integer n . Furthermore , an equivalent characterization of CE Gorenstein projective dimension of complexes is given .As applications ,it is proved that a complex existing finite CE Gorenstein projective dimension has a CE Gorenstein projective precover .关键词
