##article.abstract##

We consider the class of bipartite planar graphs Str and some problems connected to them, where r is the number of the regions of the planar graph Str. We prove that r is linked to algebraic invariants of the graph, in particular to the projective resolution of the edge ideal. [DOI: 10.1685/CSC06101] About DOI
