Graph Theory Problems and Solutions. Tom Davis. tomrdavis@earthlink.net http://www.geometer.org/mathcircles November 11, 2005. Problems. Prove that the sum of the degrees of the vertices of any nite graph is even. Show that every simple graph has two vertices of the same degree.
Soln. These look like loop graphs, or bracelets. The n = 0 graph is empty, the n = 1 is a single vertex with a loop on it, and n = 2 is two vertices with a double edge between. n = 3 is a triangle, n = 4 is a square, etc. 2.
A graph is something that looks like this. It has vertices, and edges. Each edge connects two vertices. It is used to model various things where there are ‘connections’. For example, it could be cities and roads between them, or it could be the graph of friendship between people: each vertex is a person and two people are connected by an ...
Math 110 Graph Theory Worksheet #1 1.Draw a simple graph with 4 vertices and exactly two vertices of even degree. 2.Draw a connected graph with 5 vertices which contains a bridge.
This document provides solutions to exercises on graph theory: 1) It models several situations as graphs and provides the corresponding adjacency matrices. 2) For given graphs, it determines whether they are planar and bipartite. 3) It draws example graphs matching given properties using Euler's formula.
Math 110 Graph Theory Worksheet #2 1.Sketch the complete graph on 5 vertices, K 5, with vertices labeled A, B, C, D, and E. Use Fleury’s Algorithm to nd an Euler circuit in your graph and give the circuit. 2.Determine if each of the graphs above have a Hamiltonian circuit. Explain. 3.Use Euler’s theorem to decide whether the each of the ...
