Abstract

By finding orthogonal representation for a family of simple connected called δ\delta-graphs it is possible to show that δ\delta-graphs satisfy delta conjecture. An extension of the argument to graphs of the form PΔ(G)+2G\overline{P_{\Delta(G)+2}\sqcup G} where PΔ(G)+2P_{\Delta(G)+2} is a path and GG is a simple connected graph it is possible to find an orthogonal representation of PΔ(G)+2G\overline{P_{\Delta(G)+2}\sqcup G} in RΔ(G)+1\mathbb{R}^{\Delta(G)+1}. As a consequence we prove delta conjecture.
