   Format: MarkdownItexI stumbled across some [slides](http://www.maths.manchester.ac.uk/~mprest/seoulbmr.pdf) where Michael Prest seems to be getting category theory and model theory to interact in interesting ways. The final slides describes (anti-)equivalences between three 2-categories. There should be some good things to extract by the smart people around here.
