ON THE ROOTS OF HUB POLYNOMIALS

Ragi Puthan Veettil and T. V. Ramakrishnan

Abstract:

The hub polynomial of a graph G of order n is the polynomial where denotes the number of hub sets of cardinality i and is the hub number of G. A root of the hub polynomial is called hub root of G. In this paper, we study hub roots of a certain family of graphs.
