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 …

Is the Universe an Illusion?: A review article shedding light upon one of the mind boggling paradoxes
Abstract: We use the Russell’s paradox to dive into the philosophical aspect of life that mathematically supports the philosophical statement “We are all just a thought”. Just as the wind carries the fragrance of its source, so does this article. We mention how the Zermelo-Fraenkel Set Theory came into existence and also its axioms (two of them in detail). We have also mentioned two other paradoxes, which are similar to the …
