dc.title	Left Triangulated Categories Arising from Contravariantly Finite Subcategories	en
heal.abstract	Let modLAMBDA be the category of finitely generated right LAMBDA-modules over an artin algebra LAMBDA, and F be an additive subfunctor of Ext(LAMBDA)1( , ). Let P(F) denote the fulL sucategory of A with objects the F-projective modules. If the functor F has enough F- projectives, then we show that the stable category mod(P(F))LAMBDA has a left triangulated structure. In case F = Ext(LAMBDA)1 ( , ), the above statement implies that the stable category mod(p)LAMBDA of modLAMBDA has left triangulated structure. Dual statements for the case of F-injective modules are also true.	en
