On the odd girth and the circular chromatic number of generalized Petersen graphs

Amir Daneshgar, Meysam Madani

A class of simple graphs such as $\mathcal{G}$ is said to be {\it odd-girth-closed} if for any positive integer $g$ there exists a graph $G\in \mathcal{G}$ such that the odd-girth of $G…
