Matrix Representation for Seven-Dimensional Nilpotent Lie Algebras

Abstract

Ghanam R, Basim Mustafa B, Mustafa MT and Thompson G

This paper is concerned with finding linear representations for seven-dimensional real, indecomposable nilpotent Lie algebras. We consider the first 39 algebras presented in Gong’s classification which was based on the upper central series dimensions. For each algebra, we give a corresponding matrix Lie group, a representation of the Lie algebra in terms of left-invariant vector field and left-invariant one forms.
