*From Poisson To String Geometry*

#### Posted by Urs Schreiber

The next event organized by our *Research Network String Geometry* is next week the conference:

*From Poisson to String Geometry*Erlangen, September 11 - 14 2012

(webpage)

First I didn’t plan to go myself, because I am teaching an intensive course and have some other things to look after. But after being pressed now I agreed to come just on Friday, and then talk about this:

**Higher quantomorphism groups on $n$-plectic higher stacks**n-Plectic geometry is an interpretation of the multisymplectic description of n-dimensional field theory in terms of higher algebra/higher geometry. Chris Rogers has proposed a definition of Poisson L-infinity algebras over $n$-plectic manifolds. In the talk I give a simple definition of quantomorphism n-groups over n-plectic cohesive infinity-stacks.. Then I discuss that they integrate these L-infinity algebras in the case that the $\infty$-stack is just a smooth manifold, and hence generalize them to the case that it is not. I end by indicating how for $n=2$ and $n=3$ the construction subsumes the higher gauge coupling behaviour of the open type II string and sees at least aspects of that the open membrane.

This is joint work with Chris Rogers which we will have written up by end of the year.

Roughly, I’ll be presenting the content of sections 2.6.1 and 4.4.17 of *differential cohomology in a cohesive topos*.
