HYPERBOLIC NOTIONS ON A PLANAR GRAPH OF BOUNDED FACE DEGREE
HYPERBOLIC NOTIONS ON A PLANAR GRAPH OF BOUNDED FACE DEGREE
We study the relations between strong isoperimetric inequalities and Gromov hyperbolicity on planar graphs, and give an alternative proof for the following statement: if a planar graph of bounded face degree satisfies a strong isoperimetric inequality, then it is Gromov hyperbolic. This theorem was formerly proved in the author's paper …
