Domination parameters with number 2: interrelations and algorithmic consequences
Flavia Bonomo, Bostjan Bresar, Luciano N. Grippo +2
In this paper, we study the most basic domination invariants in graphs, in which number 2 is intrinsic part of their definitions. We classify them upon three criteria, two of which…

Convex p-partitions of bipartite graphs
Luciano Grippo, Martín Matamala, Martín Safe +1
A set of vertices X of a graph G is convex if it contains all vertices on shortest paths between vertices of X. We prove that for fixed p, all partitions of the vertex set of a bip…
