Let R be a prime ring of characteristic different from 2 with extended centroid C, \(n\ge 1\) a fixed positive integer, \(F, G:R\rightarrow R\) two non-zero generalized skew derivations of R.

  1. (I)

    If \(\biggl (F(x)x\biggr )^n\in C\) for all \(x\in R\), then the following hold:

    1. (a)

      if F is an inner generalized skew derivation, then either \(R\subseteq M_2(C)\) or R is commutative;

    2. (b)

      if F is not an inner generalized skew derivation, then R is commutative.

  2. (II)

    If \([F(x)x,G(y)y]_n=0\) for all \(x,y\in R\), then R is commutative unless when \(char(R)=p > 0\), G is an inner generalized skew derivation and \(R\subseteq M_2(C)\).

具有广义偏导数的素环的幂中心值和恩格尔条件

R为质数为2的质环,质心为C\(n \ ge 1 \)为固定的正整数,(F,G:R \ rightarrow R \)R的两个非零广义偏导数。

  1. (一世)

    如果对于所有\(x \ in R \)\(\ biggl(F(x)x \ biggr)^ n \ in C \),则以下条件成立:

    1. (一个)

      如果F是内部广义偏导数,则\(R \ subseteq M_2(C)\)R是可交换的;

    2. (b)

      如果F不是内部广义偏导数,则R是可交换的。

  2. (二)

    如果\([F(x)的X,G(y)的Y] _n = 0 \)对于所有\(X,Y \中的R \) ,然后- [R是可交换的,除非当\(炭(R)= P> 0 \)G是内部广义偏导数和\(R \ subseteq M_2(C)\)
