Combinatoric and Algebraic Aspects of a Class of Planar Graphs

Monica La Barbiera

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.
