WebMar 19, 2024 · These are, in a very fundamental sense, the same graph, despite their very different appearances. Definition 26.1 (Isomorphism, a first attempt) Two simple graphs G1 = (V1, E1) and G2 = (V2, E2) are isomorphic if there is a bijection (a one-to-one and onto function) f: V1 → V2 such that if a, b ∈ V1, then there is an edge between a and b ... Two graphs G1 and G2are said to be isomorphic if − 1. Their number of components (vertices and edges) are same. 2. Their edge connectivity is retained. Note− In short, out of the two isomorphic graphs, one is a tweaked version of the other. An unlabelled graph also can be thought of as an … See more A graph ‘G’ is said to be planar if it can be drawn on a plane or a sphere so that no two edges cross each other at a non-vertex point. Example See more Two graphs G1 and G2are said to be homomorphic, if each of these graphs can be obtained from the same graph ‘G’ by dividing some edges of G with more vertices. Take a look at the following example − Divide the … See more Every planar graph divides the plane into connected areas called regions. Example Degree of a bounded region r = deg(r)= Number of edges … See more A simple connected planar graph is called a polyhedral graph if the degree of each vertex is ≥ 3, i.e., deg(V) ≥ 3 ∀ V ∈ G. 1. 3 V ≤ 2 E 2. 3 R ≤ 2 E See more
