$λ$ -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…

On the expansion constant and distance constrained colourings of hypergraphs

Annayat Ali, Rameez Raja

For any two non-negative integers h and k, h > k, an L(h, k)-colouring of a graph G is a colouring of vertices such that adjacent vertices admit colours that at least differ by h a…

L(2, 1)-labeling of some zero-divisor graphs associated with commutative rings

Rameez Raja, Annayat Ali

Let $G = (V, E)$ be a simple graph, an $L (2, 1)$ -labeling of $G$ is an assignment of labels from nonnegative integers to vertices of $\mathca…
