Structural properties of a symmetric Toeplitz and Hankel matrices
Hojin Chu, Homoon Ryu
In this paper, we investigate properties of a symmetric Toeplitz matrix and a Hankel matrix by studying the components of its graph. To this end, we introduce the notion of ``weigh…

Row graphs of Toeplitz matrices
Gi-Sang Cheon, Bumtle Kang, Suh-Ryung Kim +1
In this paper, we study row graphs of Toeplitz matrices. The notion of row graphs was introduced by Greenberg et al. in 1984 and is closely related to the notion of competition gra…

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_…
