Session topic: Equivalence Relations

Session Abstract:
We all know about functions, but in this Math Circle we will explore a more general notion of a function, called a relation. Relations are a useful concept because their inverse always exists and when they exhibit three special properties called reflexivity, symmetry, and transitivity, they become equivalence relations. We will explore what it means to be an equivalence relation and what are some useful applications of equivalence relations. In particular, we will look at equivalence classes and examine how these help us categorize our sets into more useful sets. Finally, we will look at one of the most famous uses of equivalence classes: numbers “modulo” a number. This idea is very important in number theory and we will play around with some modular arithmetic.
