### Higher Structures in Göttingen - Part II

#### Posted by John Baez

In November last year there was a little workshop in Göttingen on Higher Structures in Differential Geometry. Urs blogged about it here. In February there will be a kind of continuation:

- Higher Structures in Topology and Geometry II, February 5th and 6th, organized by Chenchang Zhu and Giorgio Trentinaglia, Courant Research Center Göttingen.

Ieke Moerdijk and I will give three lectures each. He’ll probably speak about orbifolds or stacks — I’m not sure. I’ll give talks combining the Streetfest lectures on higher gauge theory, the 2006 Barrett lectures, and a talk about classifying spaces for 2-groups.

That’s a lot of stuff to cover. Luckily I’ll be aided by Alex Hoffnung (who will introduce the sheaf-theoretic approach to smooth spaces) and Chris Rogers (who will talk about Lie 2-algebras from 2-plectic geometry).

Clemens Berger will speak on ‘Higher categories and Eilenberg-Mac Lane spaces’ — that’s sure to be interesting. And Camilo Arias Abad and David Martinez Torres will speak on subjects yet to be disclosed.

I’ve never been to Göttingen. For any mathematician who knows a little history, visiting Göttingen is a kind of pilgrimage to sacred ground! So that should be fascinating in its own right, even apart from the workshop itself.

Here are slides of the talks I’ll be giving in Göttingen. Later I’ll add links to Alex Hoffnung’s talk on smooth spaces and Chris Rogers’ talk on 2-plectic geometry and Lie 2-algebras. All these talks are supposed to fit together and form a coherent — or at least quasicoherent — introduction to higher gauge theory.

You can also see lots of references for further reading, here.
