Graph Theory 1 In the domain of mathematics and computer science, graph theory is the study of graphs that concerns with the relationship among edges and vertices. It is a popular subject having its applications in computer science, information technology, biosciences, mathematics, and linguistics to name a few. Without further ado, let us
In this chapter, we will cover a few standard examples to demonstrate the concepts we already discussed in the earlier chapters. Example 1. Find the number of spanning trees in the following graph. Solution. The number of spanning trees obtained from the above graph is 3. They are as follows −.
This tutorial offers a brief introduction to the fundamentals of graph theory. Written in a reader-friendly style, it covers the types of graphs, their properties, trees, graph traversability, and the concepts of coverings, coloring, and matching.
1-connected graphs are called connected, 2-connected are biconnected, 3-connected are triconnected, etc. Note the “exceptions”: • Singleton graph

Given a graph G,itsline graph or derivative L[G] is a graph such that (i) each vertex of L[G] represents an edge of G and (ii) two vertices of L[G] are adjacent if and only if their corresponding edges share a common endpoint (‘are incident’) in G (Fig. ??).
Graph theory Eric Shen (Friday, August 28, 2020) • A vertex vis incident to an edge e(or vice versa) if vis an endpoint of e. • A graph is connected if there is a path between every pair of distinct vertices.
