Abstract

Let kk be a field of any characteristic, VV a finite-dimensional vector space over kk, and Sd(V)S^d(V^*) be the dd-th symmetric power of the dual space VV^*. Given a linear map φ\varphi on VV and an eigenvector ww of φ\varphi, we prove that the pair (φ,w)(\varphi, w) can be used to construct a new Lie algebra structure on Sd(V)S^d(V^*). We prove that this Lie algebra structure is solvable, and in particular, it is nilpotent if φ\varphi is a nilpotent map. We also classify the Lie algebras for all possible pairs (φ,w)(\varphi, w), when k=Ck=\mathbb{C} and VV is two-dimensional.
