本文利用重元技巧研究了三角矩阵代数的Gorenstein亏范畴。首先在一定条件下构造了三角矩阵代数的Gorenstein亏范畴的左元,利用它给出了X-W所得到的三角矩阵代数的Gorenstein性质的范畴解释. Chen,B.L. Xiong和P. Zhang分别。其次,在一定的条件下,构造了三角矩阵代数的Gorenstein亏范畴的等价元。作为应用,对于一类特殊的三角矩阵代数,我们称之为单胶合代数,我们描述了它们的奇异范畴和Gorenstein亏范畴。
We apply the technique of recollement to study the Gorenstein defect categories of triangular matrix algebras. First, we construct a left recollement of Gorenstein defect categories for a triangular matrix algebra under some conditions, using it, we give a categorical interpretation of the Gorenstein properties of the triangular matrix algebras obtained by X-W. Chen, B.L. Xiong and P. Zhang respectively. Second, under some additional conditions, a recollement of Gorenstein defect categories for a triangular matrix algebra is constructed. As an application, for a special kind of triangular matrix algebras, which are called simple gluing algebras, we describe their singularity categories and Gorenstein defect categories.
