Symmetries of manifolds

Abstract: Whenever one studies a mathematical object one ought also to study its symmetries. Manifolds---spaces which look locally like ordinary Euclidean space but which can be globally complicated---are the central objects of study in topology and geometry, and their groups of symmetries come in many flavours (isometries, diffeomorphisms, homeomorphisms, ...). I will discuss some classical results about rigid symmetries, and then some recent results about the spaces of all symmetries of certain manifolds.
