摘要
研究了Cartan-Eilenberg Gorenstein AC-内射(投射)复形的若干等价刻画。证明了复形G是Cartan-Eilenberg Gorenstein AC-内射(投射)复形当且仅当G具有Cartan-Eilenberg强完全内射(L完全投射)分解。并且研究了复形的Cartan-Eilenberg Gorenstein AC-内射(投射)维数。
Some equivalent characterizations of Cartan-Eilenberg Gorenstein AC-injective(projective) complexes are studied. It is proved that a complex G is Cartan-Eilenberg Gorenstein injective(projective) if and only if G has a Cartan-Eilenberg strongly complete injective(L complete projective) resolution. Also, the Cartan-Eilenberg Gorenstein AC-injective(projective) dimension of complexes is studied.
