4th Odense Winter School on Geometry and Mathematical Physics

Posted by Urs Schreiber

I have just arrived in Denmark, where I am attending the

4th Odense Winter School on Geometry and Theoretical Physics (website, program ).

I’ll try to report in the comment section below on what’s going on.

Myself, I’ll be lecturing on Stacks, differential geometry and action functionals, following section 1.1 “Motivation” with technical details sprinkled in from section 1.3 “Models and applications” of the cohesive document.

I had given similar lectures (with roughly twice the time, though) last weekend in Warsaw, at the

Polish Seminar on Category Theory and its Applications (website)

with an accompanying homotopy type theoretic comment in the Warsaw category theory seminar on the geometric and the homotopical interval/circle in homotopy type theory (see here for what this is about).

I am trying to use these events to fine-tune the section 1. Introduction further (not that there is not lots of room to improve it). I am aware of a bunch of deficiencies of the exposition, that I am trying to find the time to fix. But there must be also a bunch of deficiencies that I am not yet aware of. If you tell me about those that bug you, I’d be very grateful. (Many thanks at this point to John Huerta, who has recently given me a list of useful feedback on this.)
