Some New Results on Seidel Equienergetic Graphs

Samir K. Vaidya, Kalpesh M. Popat

The energy of a graph $G$ is the sum of the absolute values of the eigenvalues of the adjacency matrix of $G$ . Some variants of energy can also be found in the literature which are…

Radio labelling of two-branch trees

Devsi Bantva, Samir Vaidya, Sanming Zhou

A radio labelling of a graph $G$ is a mapping $f : V (G) \to {0, 1, 2, \dots}$ such that $∣ f (u) - f (v) ∣ \geq d iam (G) + 1 - d (u, v)$ for every pair of distinct vertices $u, v$ …

Hamiltonian chromatic number of trees

Devsi Bantva, Samir Vaidya

Let $G$ be a simple finite connected graph of order $n$ . The detour distance between two distinct vertices $u$ and $v$ denoted by $D (u, v)$ is the length of a longest $uv$ -path in $…

Radio number of trees

Devsi Bantva, Samir Vaidya, Sanming Zhou

A radio labeling of a graph $G$ is a mapping $f : V (G) \to {0, 1, 2, \dots}$ such that $∣ f (u) - f (v) ∣ \geq d + 1 - d (u, v)$ for every pair of distinct vertices $u, v$ of $G$ ,…
