A matrix equation $X^{n} = a I$

Taehyeok Heo, Jihoon Choi, Suh-Ryung Kim

In this paper, we study a matrix equation $X^{n} = a I$ . We factorize $X^{n} - a I$ based upon the factorization of $x^{n} - a$ and then give a necessary and sufficient condition for one o…

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…

On the competition graphs of $d$ -partial orders

Jihoon Choi, Kyeong Seok Kim, Suh-Ryung Kim +2

In this paper, we study the competition graphs of $d$ -partial orders and obtain their characterization which extends results given by Cho and Kim \cite{chokim} in 2005. We also sho…
