Abstract
Classifying objects in mathematics is a fundamental activity. Each branch has its own natural notion of equivalence and it is equally natural to list the objects in question up to that equivalence. So, for example, we have the notions of isomorphism for vector spaces or for groups, diffeomorphism for manifolds, conjugacy for dynamical systems.
