Resumen de On t -centralizers of semiprime rings

E. Albas

• Let R be a semiprime 2-torsion free ring, and let t be an endomorphism of R. Under some conditions we prove that a left Jordan t-centralizer of R is a left t-centralizer of R. Under the same conditions we also prove that a Jordan t-centralizer of R is a t-centralizer of R. We thus generalize Zalar¿s results to the case of t-centralizers of R.
