    In this article, some structures in the projective plane of order q are found which allow us to construct small k - regular balanced bipartite graphs of girth 6 for all k ≤ q. When k = q, the order of these q-regular ...
  • Defensive alliances in regular graphs and circulant graphs 

    Araujo Pardo, M. Gabriela; Barrière Figueroa, Eulalia (2008-10)
    Article
    Open Access
    In this paper we study defensive alliances in some regular graphs. We determine which subgraphs could a critical defensive alliance of a graph $G$ induce, if $G$ is $6$-regular and the cardinality of the alliance is ...
