$λ$ -Chromatic Polynomials and Polytope Geometry

Annayat Ali, Rameez Raja

In this paper, we investigate the notion of the \textit{ $λ$ -chromatic polynomial} of a graph, which enumerates the number of distinct $L (2, 1)$ -colorings using colors from a prescri…

Group-annihilator graphs realised by finite abelian groups and its properties

Eshita Mazumdar, Rameez Raja

Let $G$ be a finite abelian group viewed a $Z$ -module and let $G = (V, E)$ be a simple graph. In this paper, we consider a graph $Γ (G)$ called as a \textit{group…
