Notes on Relative Extension Functors
The objective of this paper is to study the relative homological properties of contravariantly and covariantly finite subcategories. Some sufficient conditions for Ext¯YnA,B≃Ext¯XnA,B are obtained. We also give the conditions under which the stable categories C/W/X/W are one-side triangulated catego...
