On b-Coloring Parameters of Some Classes of Graphs
Abstract: AbstractVertex coloring has always been a topic of interest. Motivated by the studies on -chromatic mean and variance of some standard graphs, in this paper, we obtain few results for -chromatic and -chromatic mean and variance of some cycle related graph classes. Here, Vertex coloring of a graph is taken to be the random experiment. Discrete random variable for this random experiment is the color of randomly chosen vertex of …

Injective Coloring Parameters of Some Special Classes of Graphs
Abstract: AbstractThe vertex coloring of a graph can be viewed as a random experiment and with respect to this experiment, a random variable can be defined such that denotes the color of an arbitrarily chosen vertex. In this paper, we broaden the ideas of coloring mean and variance of graphs with respect to a particular type of proper injective coloring and determine these parameters for some standard graph classes.MSC2010: 05C15, 05C38. …
