摘要
介绍并研究Y-Gorenstein内射复形,证明了复形C是Y-Gorenstein内射复形当且仅当每个层次上的模Cm是YGorenstein内射模.进而给出复形的Y-Gorenstein内射维数小于等于n的若干等价刻画.
Introduce and investigate Y-Gorenstein injective complexes,prove that the complex Cis YGorenstein injective complex if and only if every termCmis Y-Gorenstein injective module.Moreover,some characterizations of Y-Gorenstein injective dimensions of complexes less than or equal to nare given.
