Abstract:
The results on Lie homomorphisms of associative algebras are extended to certain associative superalgebras. It is shown that under appropriate conditions a Lie superautomorphism of $A=A_0\oplus A_1$ is a sum of a superautomorphism or the negative of a superantiautomorphism and a central map. In particular we consider the situation when $A$ is a central simple algebra and its $\mathbb Z_2$-grading is induced by an idempotent.References
