关于Frobenius范畴的三个结果

Three results on Frobenius categories

Xiao-Wu Chen

摘要:

本文包括三个关于Frobenius范畴的结果:(1)给出了Frobenius范畴的因子范畴仍是Frobenius范畴的充分条件:(2)证明了任一Frobenius范畴等价于由某个可加范畴上的Cohen-Macaulay模构成的Frobenius范畴的扩张闭正合子范畴;这是Frobenius范畴的Gabriel-Quillen嵌入定理的类似物;(3)证明了在一定条件下,具有足够多投射对象和足够多内射对象的正合范畴允许一个自然的新正合结构,由此,给定的范畴成为弗罗贝纽斯。讨论了结果的几个应用。

英文摘要:

This paper consists of three results on Frobenius categories: (1) we give sufficient conditions on when a factor category of a Frobenius category is still a Frobenius category; (2) we show that any Frobenius category is equivalent to an extension-closed exact subcategory of the Frobenius category formed by Cohen-Macaulay modules over some additive category; this is an analogue of Gabriel-Quillen's embedding theorem for Frobenius categories; (3) we show that under certain conditions an exact category with enough projective and enough injective objects allows a natural new exact structure, with which the given category becomes Frobenius. Several applications of the results are discussed.
