2-Local Derivations on the Extended Schr?dinger-Virasoro Lie Algebra
Let(sb)be the extended Schrödinger-Virasoro Lie Algebra.A map △:(sb)→(sb)is called a 2-local derivation if for every x,y ∈(sb),there exists a derivation Dx,y of (sb)such that △(x)=Dx,y(x)and △(y)=Dx,y(y).We prove that any 2-local derivation on(sb)is a derivation.
