文摘As a non-trivial generalization of quasi-resolving subcategories,the notion of Ext-quasi-resolving subcategories of an abelian category is introduced.Moreover,we give a general example,which is not a quasi-resolving subcategory,and the homological theory of Ext-quasi-resolving subcategories is studied.In particular,we generalize many results on the resolving subcategories.
