| Abstract: | In this paper,let be a class of right R-modules closed under isomorphisms and direct summands.The relations between left(right)-dimensions and left exact functors are considered for an(injectively) coresolving class or a(projectively) resolving class .In view of those,there are some applications. |

| Keywords: | (injectively) coresolving (projectively) resolving dimensions |
