(C3, C4, C5, C7)-Free Almost Well-Dominated Graphs
The domination gap of a graph G is defined as the di erence between the maximum and minimum cardinalities of a minimal dominating set in G. The term well-dominated graphs referring to the graphs with domination gap zero, was first introduced by Finbow et

Relating the super domination and 2-domination numbers in cactus graphs
A set D⊆V(G)D\subseteq V\left(G) is a super dominating set of a graph GG if for every vertex u∈V(G)\Du\in V\left(G)\setminus D, there exists a vertex v∈Dv\in D such that N(v)\D={u}N\left(v)\setminus D=\left\{u\right\}.

Offensive alliances in cubic graphs [PDF]
An offensive alliance in a graph $\Gamma=(V,E)$ is a set of vertices $S\subset V$ where for every vertex $v$ in its boundary it holds that the majority of vertices in $v$'s closed neighborhood are in $S$.

(Independent) $k$-Rainbow Domination of a Graph
Let G = (V, E) be a graph with the vertex set V = V(G) and the edge set E = E(G). Let k be a positive integer and γrk(G) (γirk (G)) be k-rainbow domination (independent k-rainbow domination) number of a graph G.

Hereditary Equality of Domination and Exponential Domination
We characterize a large subclass of the class of those graphs G for which the exponential domination number of H equals the domination number of H for every induced subgraph H of G.

On Generalized Sierpiński Graphs
In this paper we obtain closed formulae for several parameters of generalized Sierpiński graphs S(G, t) in terms of parameters of the base graph G. In particular, we focus on the chromatic, vertex cover, clique and domination numbers.

A Note on the Locating-Total Domination in Graphs
In this paper we obtain a sharp (improved) lower bound on the locating-total domination number of a graph, and show that the decision problem for the locating-total domination is NP-complete.

On the general position number of two classes of graphs
The general position problem is to find the cardinality of the largest vertex subset SS such that no triple of vertices of SS lies on a common geodesic.
