We identify some situations where mappings related to left centralizers, derivations and generalized (α,β)-derivations are free actions on semiprime rings. We show that for a left centralizer, or a derivation T, of a semiprime ring R the mapping ψR→R defined by ψ(x)=T(x)x−xT(x) for all x∈R is a free action. We also show that for a generalized (α,β)-derivation F of a semiprime ring R, with associated (α,β)-derivation d, a dependent element a of F is also a dependent element of α+d. Furthermore, we prove that for a centralizer f and a derivation d of a semiprime ring R, ψ=d∘f is a free action.
