WebThe upper bound is called sharp if equality holds for at least one value of x. It indicates that the constraint is optimal, and thus cannot be further reduced without invalidating the inequality. Similarly, a function g defined on domain D and having the same codomain (K, ≤) is an upper bound of f, if g(x) ≥ f (x) for each x in D. WebBase. For all planar graphs with n(G) ≤ 5, the statement is correct. Inductive step. Let G have more than 5 vertices. Select a vertex v of degree ≤ 5. It always exists, since else, the number of edges in the graph would exceed the upper bound of 3p−6. By induction, graph G−v is 5-colorable. Consider a 5-coloring of G − v. bandera utah
