Operations on Covering Numbers of Certain Graph Classes

Combinatorics 2015-06-11 v1

Abstract

The bounds on the sum and product of chromatic numbers of a graph and its complement are known as Nordhaus-Gaddum inequalities. In this paper, we study the operations on the Independence numbers of graphs with their complement. We also provide a new characterization of certain graph classes.
