Theorem 11.9 Let G be a maximal outerplane graph with p > 3 vertices all lying on the exterior face. Then G has p -2 interior faces. Proof. Obviously the result holds for p = 3 . Suppose it is true for p - n and let G have p = n + 1 vertices and m interior faces. Clearly...
Every SplineCNN layer has a kernel size of 5, meaning the 2D B-spline function for the continuous kernel has 25 defining points, with 5 points on each axis. The number of nodes in the graph is arbitrary and depends on the triangulation of the shape. Each node in the graph input layer...

Base case: If GG is a graph consisting of a single vertex vv, then a planar embedding of GG has one discrete face, namely the length zero closed walk vv.Constructor Case (split a face): Suppose GG is a connected graph with a planar embedding, and suppose aa and bb are distinct, non...
A planar graphis a graph that can be drawn on a plane in such a way that no edges cross each other, and this drawing is a plane graph. For example, in Figure 1, the first graph is a complete graph of order 4, denoted by K4, which is planar graph. The second graph is an embedd...

In this note, we give a smaller example of planar graph, with 18 vertices, which is not Z 4 -colorable. The earlier example due to Král et al. [A note on group coloring, J. Graph Theory 50 (2005) 123–129] has 34 vertices....
