The cyclic sieving phenomenon (CSP) refers to the observation that one may sometimes learn about a cyclic action on a finite set X by evaluating a natural q-analogue X(q) of |X| at roots of unity. It was introduced by Reiner, Stanton and White.

I will talk about some methods for finding CSPs, including their connection to the representation theory of general linear groups and symmetric groups.
