令R是非交换的素环,I是环R的非零右理想,g是R的广义导子,满足[g(rk),rk]n =0, r∈I,k,n是固定的正整数,则存在c∈U,U是环R的右Utumi商环,对适当的α∈C,满足g( x)=cx,且(c -α)I =0,特别地,有g(x)=xα,x∈I.

Let R be a noncommutative prime ring , I be a nonzero right ideal of R, and g be a generalized derivation of R, such that [g(rk),rk]n =0 for all r∈I, where k and n are fixed positive integers.Then there exists c∈U, U is the right Utumi quotient ring of R, such that g( x)=cx and ( c-α) I=0 for a suitable α∈C.In particular we have that g( x)=xα,x∈I.
