素超代数的广义超导子和局部广义超导子

GENERALIZED SUPERDERIVATIONS AND LOCAL GENERALIZED SUPERDERIVATIONS IN A PRIME SUPERALGEBRA

本文研究了含有非平凡幂等元的素超代数A上广义超导子和局部广义超导子的问题.利用引入幂等元的方法,证明了A上的局部广义超导子均是广义超导子,并给出了A上广义超导子的一个刻画,推广了Foner和王宇的结果.

In this paper, we study generalized superderivations and local generalized superderivations in a prime superalgebra A with a nontrivial idempotent. By using the method of introducing idempotents, we prove that every local generalized superderivation is a generalized superderivation and give a characterization of generalized superderivations in A, which generalize the results of Foner and Wang.
