2x2 Matrices

Giles Gardam

Abstract

We will explore the many guises under which groups of 2x2 matrices appear, such as isometries of the hyperbolic plane, mapping class groups and the modular group. Along the way we will learn some interesting and perhaps surprising facts.

Modern software allows us to draw symbols (such as Chinese characters, or mathematical symbols) that the computer will then recognise and turn into type. How can these systems be improved, so that they run faster and more accurately?
