Özet
Given a ring R, we investigate a subfunctor Z* of the identity functor on the category of all right R-modules which is defined by Z* (M) = {m is an element of M: mR is a small module}, for any R-module M. We prove that if the ring R satisfies the descending chain condition for right annihilators and RIP is an Artinian ring for every primitive ideal P then Z*(M) = {m is an element of M: mS = 0} for every right R-module M, where S is the left socle of R. Moreover the ring R is semiprime Artinian if and only if R is right bounded, R satisfies the descending chain condition for right annihilators and Z*(M) = 0 for some faithful right R-module M.
