Abstract

The present paper is devoted to studying local derivations on the Lie algebra W(2,2)W(2,2) which has some outer derivations. Using some linear algebra methods in \cite{CZZ} and a key construction for W(2,2)W(2,2) we prove that every local derivation on W(2,2)W(2, 2) is a derivation. As an application, we determine all local derivations on the deformed bms3\mathfrak{bms}_3 algebra.
