Planarity of generalized ladder graphs
Hojin Chu, Suh-Ryung Kim, Homoon Ryu
The Cartesian product of P_2 and P_n is called an n-ladder graph for a positive integer n. We call two paths P_m and P_n together with some edges each of which joins a vertex on P_…
Structural properties of Toeplitz graphs
Seyed Ahmad Mojallal, Ji-Hwan Jung, Gi-Sang Cheon +2
In this paper, we study structural properties of Toeplitz graphs. We characterize -free Toeplitz graphs for an integer and give equivalent conditions for a Toeplitz…
On -step competition graphs of bipartite tournaments
Jihoon Choi, Soogang Eoh, Suh-Ryung Kim +1
In this paper, we study -step competition graphs of bipartite tournaments. A bipartite tournament means an orientation of a complete bipartite graph. We show that the $(1,2)…
On the phylogeny graphs of degree-bounded digraphs
Seung Chul Lee, Jihoon Choi, Suh-Ryung Kim +1
Hefner [K. A. S. Hefner, K. F. Jones, S. -R. Kim, R. J. Lundgren and F. S. Roberts: competition graphs, Discrete Applied Mathematics, 32, (1991) 241-262] characterized acyc…
On consecutive edge magic total labeling of connected bipartite graphs
Bumtle Kang, Suh-Ryung Kim, Ji Yeon Park
Since Sedlá$\breve{\mbox{c}}$ek introduced the notion of magic labeling of a graph in 1963, a variety of magic labelings of a graph have been defined and studied. In this paper, we…
