Abstract

The graph whose vertices are the elements in a Dihedral group of order n is called a Co-prime graph, and it is denoted by Γ(D_2n ), such that two vertices x and y are adjacent Γ(D_2n ), if gcd(order(x),order(y))=1, where order(x) is the order of x. In this work, we study the chromatic number, the chromatic polynomial, and the chromaticity (chromatic uniqueness) of the Co-prime graph, Γ(D_2n ).
