Unbounded face
Although a plane graph has an external or unbounded face, none of the faces of a planar map has a particular status. Planar graphs generalize to graphs drawable on a surface of a given genus. In this terminology, planar graphs have genus 0, since the plane (and the sphere) are surfaces of genus 0. See "graph … See more In graph theory, a planar graph is a graph that can be embedded in the plane, i.e., it can be drawn on the plane in such a way that its edges intersect only at their endpoints. In other words, it can be drawn in such a way that … See more Kuratowski's and Wagner's theorems The Polish mathematician Kazimierz Kuratowski provided a characterization of planar graphs in … See more Maximal planar graphs A simple graph is called maximal planar if it is planar but adding any edge (on the given vertex set) would destroy that property. All faces (including the outer one) are then bounded by three edges, explaining the … See more • Combinatorial map a combinatorial object that can encode plane graphs • Planarization, a planar graph formed from a drawing with … See more Euler's formula Euler's formula states that if a finite, connected, planar graph is drawn in the plane without any … See more Enumeration of planar graphs The asymptotic for the number of (labeled) planar graphs on $${\displaystyle n}$$ vertices is See more An apex graph is a graph that may be made planar by the removal of one vertex, and a k-apex graph is a graph that may be made planar by the removal of at most k vertices.

WebBy convention, we also count the unbounded area outside the whole graph as one face. The boundary of a face is the subgraph containing all the edges adjacent to that face and a boundarywalk is a closed walk containing all of those edges. The degreeof the face is the minimum length of a boundary walk. For example, in the figure below, the WebThe face with unbounded area is known as the unbounded face, the outer face, or the infinite face.
