Title: How to invert well-pointed endofunctors
Abstract: In 1980, Max Kelly showed that many transfinite constructions of free objects can be reduced to the special case of free algebras for well-pointed endofunctors. This yields - in a fairly simple way - a recipe to construct certain kinds of (enriched) localisations. I'll talk about how this works, before observing that this generalises constructions of Keller, Seidel, and Chen--Wang in representation theory and symplectic geometry. I'll relate this (in a rather naive way!) to a very general construction of spectra, which are, similarly, a way to invert endofunctors. If there's time or appetite, I can also say a few things about cospectra.
