摘要

设R为素环,U为Utumi商环,Q为R的Martindale商环。设d是R和m的导数,n是固定的正整数。在本文中,我们研究了下列条件之一成立的情况:(i) d(x) * n d(y)=x * m y (ii) d(x) * m d(y)=(d(x * y)))对于R的某些适当子集中的所有x, y,我们还研究了R是半素环的情况。最后,作为一个应用,我们将我们的结果应用于Banach代数上的连续导数。

A note on derivations in rings and Banach algebras
Let R be a prime ring with U the Utumi quotient ring and Q be the Martindale quotient ring of R, respectively. Let d be a derivation of R and m,n be fixed positive integers. In this paper, we study the case when one of the following holds: (i) d(x) ◦n d(y)=x ◦m y (ii) d(x) ◦m d(y)=(d(x ◦ y)) for all x, y in some appropriate subset of R. We also examine the case where R is a semiprime ring. Finally, as an application we apply our result to the continuous derivations on Banach algebras.
