Definition of complete graph
From the definition, the complete graph Kn is n − 1 -regular . That is, every vertex of Kn is of degree n − 1 . Suppose n is odd. Then n − 1 is even, and so Kn is Eulerian . Suppose n is even. Then n − 1 is odd. Hence for n ≥ 4, Kn has more than 2 odd vertices and so can not be traversable, let alone Eulerian .25 ene 2023 ...

Complete Graph: When each pair of vertices are connected by an edge then such graph is called a complete graph. Planar graph: …A finite graph is planar if and only if it does not contain a subgraph that is a subdivision of the complete graph K 5 or the complete bipartite graph K 3,3 (utility graph). A subdivision of a graph results from inserting vertices into edges (for example, changing an edge • —— • to • — • — • ) zero or more times.Oct 12, 2023 · A graph that is determined by its chromatic polynomial is said to be a chromatically unique graph; nonisomorphic graphs sharing the same chromatic polynomial are said to be chromatically equivalent. The following table summarizes the chromatic polynomials for some simple graphs. Here is the falling factorial. The graph G G of Example 11.4.1 is not isomorphic to K5 K 5, because K5 K 5 has (52) = 10 ( 5 2) = 10 edges by Proposition 11.3.1, but G G has only 5 5 edges. Notice that the number of vertices, despite being a graph invariant, does not distinguish these two graphs.
