We introduce the notion of n -homoderivation on a ring id="M3"> ℜ and show that semiprime id="M4"> must have nontrivial central ideal if it admits an appropriate id="M5"> which is centralizing some one-sided ideal. Under similar hypotheses, we prove commutativity in prime rings.

A number of algorithms have been recently proposed for distributed constraint optimization problems (DCOP). Fully decentralized examples include ADOPT [11] (search) or DPOP [12] (dynamic programming). Difficult optimization problems have been shown to require important amounts of communication when these algorithms are used (large number of small messages for ADOPT, or few but large messages fo...

The purpose of this research paper is to investigate the impact Human Resource Information Systems (HRIS) on organizational performance. HRIS are digital platforms that help organizations manage human resources by centralizing, organizing, and automating processes related HR functions. This study examines relationship between implementation performance, specifically focusing efficiency, effecti...

Let I be a non-zero left ideal of r-ring M satisfying the condition alpha b beta c= c for all a,b,c, e and alpha, r. We show that contains non-trivial central if is semiprime which admits an appropriate derivations on I, also commutative prime admitting centralizing derivation I. next give some characterizations when generalized act as homomorphisms anti-homomorphisms or two-sided ideals gamma ...
