摘要: 令A是有足够投射对象的阿贝尔范畴,X是A的关于同构封闭且包含投射对象的类。本文主要研究在什么条件下Frobenius函子保持对象的X -Gorenstein投射维数,并且证明Frobenius函子保持对象的Ding投射维数。

关键词: X -Gorenstein投射对象, Forbenius函子, X -Gorenstein投射维数, Ding投射对象

Abstract: let A be an abelian category with enough projective objects, and let X be a class of objects in A closed under isomorphism and containing the projective objects. The main purpose of this paper is to study under what conditions the Frobenius functors preserve the X -Gorenstein projective dimension of objects, and the conclusion that the Frobenius functors preserve the Ding projective dimension of objects is proved.

Key words: X -Gorenstein projective objects, Frobenius functors, X -Gorenstein projective dimension, Ding projective objects
