## Graph Theory as the Base of Four Color Theorem

Graphs Graph is a structure of a number of points and their connections within. The points are called Vertices (Vertex in singular). Connections are called Edges. Planner Graphs are those where the vertices can be placed in a way so that no edge will go over other edges. Planner graph can be drawn on a …

## History of Four Color Theorem

This is one of the most famous mathematical theories or problems. Many years were spent for finding the solution of this at least 150-year old problem. Mathematicians and some curious amateurs thought on this in different times. Some could not find any solution and some others, in their own words, did find the solution. Sometimes, …

## Pigeonhole Principle

Pigeonhole Principle is one of the interesting counting principle theories in Mathematics. The principle says, if there is k+1 pigeons and k holes then, there will be one hole with more than one pigeons. In general, the principle is: if there are n+k pigeons and k holes then, there will be n/k or more pigeons …
