Local and 2-local derivations of Block Lie algebras B(q)
We prove that every local or 2-local derivation of the Block Lie algebra $\B(q)$, with both basis indices in $\Z$, is a derivation for all $q\in\C$. The proofs use the known description of ordinary derivations, Laurent polynomials, and coefficient comparisons.
