Abstract

We show that any connected regular graph with d 1 distinct eigenvalues and odd-girth 2d 1 is distance-regular, and in particular that it is a generalized odd graph.

Keywords: distance-regular graphs, generalized odd graphs, odd-girth, spectra of graphs, spectral excess theorem, spectral characterization

JEL Classification: C0
