Admissibility conditions and asymptotic behavior of strongly regular graphs
Vasco Moço Mano, Luís António de Almeida Vieira · 2011
Let G be a strongly regular graph with three distinct eigenvalues and A its adjacency matrix. We associate a three dimensional Euclidean Jordan algebra to A and establish new admissibility inequalities on the parameters and spectrum of G. Finally, we extract some asymptotic conclusions about the spectrum of G.
