INVESTIGATING THE PROPERTIES OF DUPLICATION AND SWITCHING IN DIVISOR CORDIAL GRAPHS

Abstract

Cordial graphs, a class of graphs introduced in 1987, have been a topic of interest in graph theory. This paper explores various properties and characteristics of cordial graphs, including their relationship with other types of graphs and specific conditions for their cordiality. The study also investigates cordiality in different graph structures and provides insights into the conditions under which certain graphs can be classified as cordial.
