The notion of essential dimension was introduced by Buhler and Reichstein in the late 90s. Roughly speaking, the essential dimension of an algebraic object is the minimal number of algebraically independent parameters one needs to define the object. In this talk, we introduce the notion of essential dimension of an algebraic structure and discuss its meaning with various examples. In particular, we explain some recent results on the essential dimension of central simple algebras.
