WebRegular Graph: A graph is said to be regular or K-regular if all its vertices have the same degree K. A graph whose all vertices have degree 2 is known as a 2-regular graph. A complete graph K n is a regular of degree n-1. Example1: Draw regular graphs of degree 2 and 3. Solution: The regular graphs of degree 2 and 3 are shown in fig: Webgraph theory, branch of mathematics concerned with networks of points connected by lines.

In the mathematical field of graph theory, the Erdős–Rényi model refers to one of two closely related models for generating random graphs or the evolution of a random network. These models are named after Hungarian mathematicians Paul Erdős and Alfréd Rényi, who introduced one of the models in 1959. Edgar Gilbert introduced the other model contemporaneously and independently of Erdős a… WebChromatic Polynomials for Graphs. The chromatic polynomial of a graph G is the polynomial C G ( k) computed recursively using the theorem of Birkhoff and Lewis. The theorem of Birkhoff and Lewis states: c G ( k) = c G − e ( k) − c G / e ( k) where e is any edge from G, and. G − e is the graph obtained from G by removing edge e. takpojdsnamaWebnumber of vertices in a graph, e = E to denote the number of edges in a graph, and f to denote its number of faces. Using these symbols, Euler’s showed that for any connected planar graph, the following relationship holds: v e+f =2.
