New transmission irregular chemical graphs

Kexiang Xu, Jing Tian, Sandi Klavžar

The transmission of a vertex $v$ of a (chemical) graph $G$ is the sum of distances from $v$ to other vertices in $G$ . If any two vertices of $G$ have different transmissions, then…

On the general position numbers of maximal outerplanar graphs

Jing Tian, Kexiang Xu, Daikun Chao

A subset $R \subseteq V (G)$ of a graph $G$ is a general position set if any triple set $R_{0}$ of $R$ is non-geodesic in $G$ , that is, no vertex of $R_{0}$ lies on any geodesic between…
