Every monomorphism of the Lie algebra of unitriangular polynomial derivations is an automorphism [PDF]
We prove that every monomorphism of the Lie algebra $\ggu_n$ of unitriangular derivations of the polynomial algebra $P_n=K[x_1,..., x_n]$ is an automorphism.

Deformed higher rank Heisenberg-Virasoro algebras [PDF]
In this paper, we study a class of infinitesimal deformations of the centerless higher rank Heisenberg-Virasoro algebras. Explicitly, the universal central extensions, derivations and isomorphism classes of these algebras are determined.

The derivation algebra and automorphism group of the (generalized) twisted N=2 superconformal algebra [PDF]
In this paper, we determine the derivation algebra and automorphism group of the twisted N=2 superconformal algebra. Then we generalize the relative results to the generalized twisted N=2 superconformal algebra in the final section.
