函子范畴与k-范畴

证明了k上小范畴(G-范畴)的函子范畴仍为k上小范畴(G-范畴).

A Modular Representation of K-root-and Jacobson Structure Theorems for Additive Categories

In this paper,we give definition and moduler representation of Kothe root for additive cate gories.Using these results,get inner representation of J-root and fully homomorph class of Jscmisimple additive categories.

k上G-分次范畴的局部化

讨论k范畴,k上G-范畴,k上G-分次范畴在局部化下相应范畴的保持问题,考虑k上G-分次范畴的冲积范畴与局部化的关系,证明了[S-1]#G≌(#G)[S-1].

关于k-Abel范畴的一点注记

以一个例子为导入,给出Abel范畴中的Fitting引理、Krull-Schmidt定理的简单证明,进而得出k-Abel范畴中有限长度的不可分解对象的自同态环的计算公式.
