Graphs and and two-step nilpotent Lie algebras
Published 12 Oct 2013 in math.DG and math.RA | (1310.3414v1)
Abstract: We consider a method popular in the literature of associating a two-step nilpotent Lie algebra with a finite simple graph. We prove that the two-step nilpotent Lie algebras associated with two graphs are Lie isomorphic if and only if the graphs from which they arise are isomorphic.
