The Resolution Dimension with Respect to a Resolving Subcategory over Triangular Matrix Rings
摘要
Let T=(A0 UB)be a triangular matrix ring with A,B rings and U a B-A-bimodule.We construct resolving subcategories of T-Mod from those of A-Mod and B-Mod.Then we give an estimate of the global resolving resolution dimension of T in terms of that of A and of B.Some applications of these results are given.
