Gromov hyperbolicity of periodic planar graphs.
"Acta Mathematica Sinica-English Series", v. 30
The study of hyperbolic graphs is an interesting topic since the hyperbolicity of a geodesic metric space is equivalent to the hyperbolicity of a graph related to it. The main result in this paper is a very simple characterization of the hyperbolicity of a large class of periodic planar graphs.
