In this paper, we describe the monophonic sets in the join and composition of two connected graphs and the composition G[K"n] of a connected graph.Expand

In this paper, the m-hull sets in the join and composition of two connected graphs are characterized and their m-Hull numbers are shown to be direct consequences of these characterizations.Expand

In this paper, a new method of curve-fitting analysis is introduced, and applied to several sigmoidal-type models in order to come up with an estimate of the accumulated number of COVID-19 positive… Expand

Let G be a graph. A subset S of ) (G V is a restrained 2-dominating set if every vertex of S G V \ ) ( is adjacent to at least two vertices of S and every vertex of S G V \ ) ( is adjacent to at… Expand
