强n-Gorenstein C-投射模和内射模

Strongly n-Gorenstein C-projective and injective modules

研究了强n-Gorenstein C-投射模和强n-Gorenstein C-内射模的性质,证明了对Bass类中的任意模M和非负整数n,模M的Gorenstein C-投射维数不超过n当且仅当M是某个强n-Gorenstein C-投射模的直和因子.

Some properties of strongly n-Gorenstein C- For arbitrary module M E Bc （R） and nonnegative dimension of M is not larger than n if and only if M projective module. projective and injective modules are investigated. integral number n, the Gorenstein C-projective is direct summand of a strongly n-Gorenstein C-projective module.
