Quartic graphs which are Bakry-Émery curvature sharp

Quartic graphs which are Bakry-Émery curvature sharp

We give a classification of all connected quartic graphs which are (infinity) curvature sharp in all vertices with respect to Bakry-Émery curvature. The result is based on a computer classification by F. Gurr and L. Watson May and a combinatorial case by case investigation.
