摘要
R是中心为Z(R)的2-扭自由素环,f和g为R上的非零广义导子,d,h分别为f和g的非零伴随导子.若有(i)f(x)y=xg(y);(ii)f(xy)-xy∈Z;(iii)f(xy)-yx∈Z;(iv)f(x)f(y)-xy∈Z,则R是交换环.
Let Rbe a 2-torsion free prime ring.Radmites nonzero generalized derivations f and g with nonzero derivation dand h.if(i)f(x)y = xg(y);(ii)f(xy)-xy ∈ Z;(iii)f(xy)-yx ∈Z;(iv)f(x)f(y)-xy ∈Z,then Ris commutative ring.
