Some invariants related to threshold and chain graphs

Rameez Raja, Samir Ahmad Wagay

Let G = (V, E) be a finite simple connected graph. We say a graph G realizes a code of the type 0^s_1 1^t_1 0^s_2 1^t_2 ... 0^s_k1^t_k if and only if G can obtained from the code b…

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…
