Chromatic sum equations for rooted cubic planar maps
Authors:Yanpei Liu
Institution:(1) Institute of Applied Mathematics, Academia Sinica, China
Abstract:This paper provides a functional equation satisfied by rooted nearly cubic planar maps. By a nearly cubic map is meant such a map that all the vertices have valency 3 with the exception of at most the root-vertex. And, as a consequence, the corresponding functional equation for rooted cubic planar maps is found.
