Graph theory vertex degree
Did you know?
WebAn internal vertex(or inner vertex) is a vertex of degreeat least 2. Similarly, an external vertex(or outer vertex, terminal vertexor leaf) is a vertex of degree 1. A branch vertexin a tree is a vertex of degree at least 3. [19] Web22. This construction will yield vertices of even degree and so by Thm 19.1, graph is face 2-colorable. 7.
