Revision as of 11:40, 20 April 2014

We discuss in class colorings of graphs, where adjacent vertices have different colors. Suppose you took the graph to be a polygon and allowed the graph to be reflected and rotated. How many different colorings do you get?

Introduction

In graph theory, it is sometimes necessary to find the number of ways to color the vertices of a polygon. Two theorems that work together to solve this problem are the Polya theorem and Burnside theorem. 


Example 1:  Square


Definitions:

  • Burnside
  • Polya


Formula:

  • show formula
  • breakdown of each element
  • relate back to example 1
