Point determining digraphs, ${0, 1}$ -matrix partitions, and dualities in full homomorphisms

Pavol Hell, César Hernández-Cruz

We prove that every point-determining digraph $D$ contains a vertex $v$ such that $D - v$ is also point determining. We apply this result to show that for any ${0, 1}$ -matrix $M$ , w…

On edge-sets of bicliques in graphs

Marina Groshaus, Pavol Hell, Juraj Stacho

A biclique is a maximal induced complete bipartite subgraph of a graph. We investigate the intersection structure of edge-sets of bicliques in a graph. Specifically, we study the a…
