Chromatic bounds for the subclasses of $p K_{2}$ -free graphs

Athmakoori Prashant, S. Francis Raj, M. Gokulnath

The concept of $χ$ -binding functions for classes of free graphs has been extensively studied in the past. In this paper, we improve the existing $χ$ -binding function for $\{2K_2, K…

Bounds for the b-chromatic number of powers of hypercubes

P. Francis, S. Francis Raj, M. Gokulnath

The b-chromatic number $b (G)$ of a graph $G$ is the maximum $k$ for which $G$ has a proper vertex coloring using $k$ colors such that each color class contains at least one vertex…
