Local and $2$ -local automorphisms of simple generalized Witt algebras

Yang Chen, Kaiming Zhao, Yueqiang Zhao

In this paper, we prove that every invertible $2$ -local or local automorphism of a simple generalized Witt algebra over any field of characteristic $0$ is an automorphism. In parti…

local derivations on Witt algebras

Yang Chen, Kaiming Zhao, Yueqiang Zhao

In this paper, we prove that every local derivation on Witt algebras $W_{n}, W_{n}^{+}$ or $W_{n}^{++}$ is a derivation for any $n \in N$ . As a consequence, we obtain that every lo…

2-local derivations on Witt algebras

Yueqiang Zhao, Yang Chen, Kaiming Zhao

In this paper, we prove that every 2-local derivation on Witt algebras $W_{n}, W_{n}^{+}$ or $W_{n}^{++}$ is a derivation for all $n = 1, 2, \dots, \infty$ . As a consequence we obtain that ev…
