k-线性范畴是有限维k-代数的自然推广.设C=C1凵MC2是k-线性三角矩阵范畴,首先证明k-线性三角矩阵范畴C是三角矩阵代数的自然推广,然后研究左C模范畴,证明了cMod同构于三元组范畴CT,并利用Hom函子与函子的伴随关系,得到CMod同构于三元组范畴C■,推广了经典的三角矩阵代数的模范畴理论.
The notion of k-linear categories is a generalization of finite dimensional k-algebras. Let C=C1凵MC2 be a k-linear trtangular matrix category. In this paper it is showed that the notion of a k-linear triangular matrix category C is a generalization of a triangular nmatrix algebra,then it is proved that the left module category c Mod is isomphic to the triple category cT, which generalizes the classical theory on module category of a triangular matrix algebra.
