چکیده
|
Triangular matrix rings are examples of trivial extensions. In this article, we describe the superderivations of the trivial extensions and upper triangular matrix rings, and thereby answer a question posed by Ghahramani et al. in the context of the rings above. Moreover, we show that every super-biderivation of these rings is a biderivation, and a question is posed on superbiderivations of Z2graded rings. One of Ghahramani et al.’s results is also generalized.
