Inner derivations of simple Lie pencils of rank 1
We prove that simple Lie pencils of rank 1 over an algebraically closed field P of characteristic 0 with operators of left multiplication being derivations are of the form of a sandwich algebra M 3(U,D′), where U is the subspace of all skew-symmetric matrices in M 3(P) and D′ is any subspace containing 〈E〉 in the space of all diagonal matrices D in M 3(P).
