On $(1, 2)$ -step competition graphs of bipartite tournaments

Jihoon Choi, Soogang Eoh, Suh-Ryung Kim +1

In this paper, we study $(1, 2)$ -step competition graphs of bipartite tournaments. A bipartite tournament means an orientation of a complete bipartite graph. We show that the $(1,2)…

Competition numbers of planar graphs

Jihoon Choi, Soogang Eoh, Suh-Ryung Kim

In this paper, we relate the competition number of a graph to its edge clique cover number by presenting a tight inequality $k (G) \geq θ_{e} (G) - ∣ V (G) ∣ + k (G)$ where $θ_{e} (G)$ …
