An explicit formula for the distance characteristic polynomial of threshold graphs

Published 7 Nov 2018 in math.CO | (1811.03061v1)

Abstract: A threshold graph G on n vertices is defined by binary sequence of length n. In this paper we present an explicit formula for computing the distance characteristic polynomial of a threshold graph from its binary sequence. As application, we show a several of nonisomorphic pairwise threshold graphs which are {D}-cospectral graphs.
