T-partition systems and travel groupoids on a graph
Jung Rae Cho, Jeongmi Park, Yoshio Sano
The notion of travel groupoids was introduced by L. Nebeský in 2006 in connection with a study on geodetic graphs. A travel groupoid is a pair of a set and a binary operation $…

On the competition graphs of -partial orders
Jihoon Choi, Kyeong Seok Kim, Suh-Ryung Kim +2
In this paper, we study the competition graphs of -partial orders and obtain their characterization which extends results given by Cho and Kim \cite{chokim} in 2005. We also sho…
