A nonempty subset $ D $ of vertices in a graph $ \Gamma = (V, E) $ is said is an offensive alliance, if every vertex $ v \in \partial(D) $ satisfies $ \delta_D(v) \geq \delta_{\overline{D}}(v) + 1 $; the cardinality of a minimum offensive alliance of

Let Γ(V,E) be a simple connected graph with more than one vertex, without loops or multiple edges. A nonempty subset S⊆V is a global offensive alliance if every vertex v∈V−S satisfies that δS(v)≥δS¯(v)+1. The global offensive alliance num

Often for understanding a structure, other closely related structures with the former are associated. An example of this is the study of hyperspaces. In this paper, we give necessary and sufficient conditions for the existence of finitely-dimensional

Transitivity on graphs is a concept widely investigated. This suggest to analyze the action of automorphisms on other sets. In this paper, we study the action on the family of γ-sets (minimum dominating sets), the graph is called γ-transitive if gi

In this paper, we establish sufficient and necessary conditions for the existence of abelian subgroups of maximal order of a finite group G G , by means of its commuting graph. The order of these subgroups attains the bound c = ∣ [ x 1 ] ∣ + ⋯

La matemática es un universo de conexiones entre conceptos, teoremas y procedimientos e, incluso, se conciben como características de la disciplina conexiones no solo internas sino con otras disciplinas. Dichas conexiones matemáticas juegan un pap
