摘要: 设R是环, m,n是非负整数, m≤n. 证明(GFCm,Pn,Pm∩GFCn)是范畴GFCn中的遗传Hovey三元组, 其对应的同伦范畴是(GFCmPm)/(PmPm)=GFC/P, 其中Pn,GFCn分别表示投射维数不超过n和Gorenstein FC投射维数不超过n的模类.

Abstract: Let R be a ring, m and n be no-negative integers with m≤n. We prove that the triple (GFCm,Pn,Pm∩GFCn) is a hereditary Hovey triple in category GFCn, the corresponding homotopy category is (GFCmPm)/(PmPm)=GFC/P, where Pn is the class of modules of projective dimension ≤n and GFCn is the class of modules of Gorenstein FC projective dimension ≤n.

Key words: Gorenstein FC-projective module, exact model structure, cotorsion pair
