A set $S$ of vertices in a graph $G=(V,E)$ is called a total$k$-distance dominating set if every vertex in $V$ is withindistance $k$ of a vertex in $S$. A graph $G$ is total $k$-distancedomination-critical if $gamma_{t}^{k} (G - x) < gamma_{t}^{k}(G)

A clique of a graph G is a set of pairwise adjacent vertices of G. A clique-coloring of G is an assignment of colors to the vertices of G in such a way that no inclusion-wise maximal clique of size at least two of G is monochromatic. An equitable cli

In this study, we investigate the different spillover levels of economic policy uncertainty (EPU) on the oil, gold, and stock markets in China. EPU has the highest levels of the growth and volatility spillover on the gold market, and EPU transmits th

A dominating set of a graph G is a subset D ⊆ V (G) such that every vertex not in D is adjacent to at least one vertex in D. A dominating set S of G is called a secure dominating set if each vertex u ∈ V (G) \ S has one neighbor v in S such that

The study of optical orthogonal codes has been motivated by an application in an optical code-division multiple access system. From a practical point of view, compared to one-dimensional optical orthogonal codes, two-dimensional optical orthogonal co

Given two real numbers \(b\ge a>0\), an (a, b)-Roman dominating function on a graph \(G=(V,E)\) is a function \(f:V\rightarrow \{0,a,b\}\) satisfying the condition that every vertex v for which \(f(v)=0\) is adjacent to a vertex u for which \(f(u)=b\
