  • Graphs attaining the upper bound on the isolation number 

    Lemanska, Magdalena; Mora Giné, Mercè; Souto Salorio, María josé (Universidad de Cádiz, 2023)
    Conference report
    Open Access
    A set D of vertices of a graph is isolating if the set of vertices not belonging to D or not having a neighbour in D is independent. The isolation number of a graph G, denoted by ¿(G), is the minimum cardinality of an ...
