Motivated by Berge perfect graphs, we define star-perfect graphs and characterize them. For a finite simple graph G(V, E), let [Formula: see text] denote the minimum number of induced stars contained in G such that the union of their vertex sets is V

Introduction Prior studies on public attitudes and awareness of clinical research (CR) in India before the pandemic identified significant knowledge gaps. Thus, we aim to investigate if the pandemic has influenced awareness and attitudes towards CR g

In this paper, the study of sum signed graphs is continued. The balancing and switching nature of the graphs are analyzed. The concept of \(rna\) number is revisited and an important relation between the number and its complement is established.

For $p\in(0,1]$, a set $S\subseteq V$ is said to $p$-dominate or partially dominate a graph $G = (V, E)$ if $\frac{|N[S]|}{|V|}\geq p$. The minimum cardinality among all $p$-dominating sets is called the $p$-domination number and it is denoted by $\g

Abstract Wind energy is an energy source that is naturally clean, safe and cheap. It comes from a variety of sources. The electric energy generated by a wind turbine manifests as kinetic energy throughout the earth. The energy received from the wind

The induced \(nK_2\) decomposition of infinite square grids and hexagonal grids are described here. We use the multi-level distance edge labeling as an effective technique in the decomposition of square grids. If the edges are adjacent, then their co

The vertex distance complement (VDC) matrix \(\textit{C}\), of a connected graph \(G\) with vertex set consisting of \(n\) vertices, is a real symmetric matrix \([c_{ij}]\) that takes the value \(n - d_{ij}\) where \(d_{ij}\) is the distance between
