Matrix periods and competition periods of Boolean Toeplitz matrices

Gi-Sang Cheon, Bumtle Kang, Suh-Ryung Kim +1

In this paper, we study the matrix period and the competition period of Toeplitz matrices over a binary Boolean ring $B = {0, 1}$ . Given subsets $S$ and $T$ of $\{1,\ldot…

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_…

On Toeplitz graphs being line graphs

Gi-Sang Cheon, Bumtle Kang, Suh-Ryung Kim +2

A Toeplitz graph $T_{n} ⟨ t_{1}, t_{2}, \dots, t_{k} ⟩$ is a simple graph with the vertex set $[n]$ such that two vertices $v$ and $w$ are adjacent if and only if $∣ v - w ∣ = t_{i}$ fo…
