摘要 研究了半素环上的左Jordan导子.利用半素环的性质和已有结论证明了R为一2-非挠的半素环,若D为R→R的左Jordan导子,则D为R→Z(R)上的一个导子. Left Jordan derivation on semisimple rings is studied.Using the properties of semiprime ring and the existed results,it is proved that if R is a 2-torsion free semiprime ring and D is a left Jordan derivation of RR,then D is a derivation which maps R to Z(R).
