Enumerating planar locally finite Cayley graphs
Abstract
Description
We characterize the set of planar locally finite Cayley graphs, and give a finite representation of these graphs by a special kind of finite state automata called labeling schemes. As a result, we are able to enumerate and describe all planar locally finite Cayley graphs of a given degree. This analysis allows us to solve the problem of decision of the locally finite planarity for a word-problem-decidable presentation.
Keywords: vertex-transitive, Cayley graph, planar graph, tiling, labeling scheme
