Re: String and ChernSimons Lie 3Algebras
I’ll see you in Vienna! I’m staying at the Pension ANI, Kinderspitalgasse 1, 9th district — arriving on Saturday the 18th and leaving on Sunday the 26th. I seem to recall you’re staying there too. My wife won’t be coming along, so I’ll be free for endless conversations.
Do you know when you’re giving your talk? I don’t see you on this schedule, but that may cover only the “Poisson geometry and sigmamodels” section of the workshop — it’s a bit confusing. I’m speaking on Wednesday the 22nd at 9 am. Too bad your talk isn’t right after that: I’m talking about Lie 2algebras, while you’re doing Lie 3algebras!
Re: String and ChernSimons Lie 3Algebras
I have received a couple of comments on my slides.
Apart from a general dislike of the overlay functionality (I’ll drop that in my next slides talk, I promise! :) there was generally a desire to understand more of the details behind the stuff which I mention.
As a reaction to that, I have now included a couple of hyperlinks inside the pdf of the talk (new version here:
String and ChernSimons Lie 3Algebras
)
which lead those who follow them to slides which contain a little more details (and which contain a “back” button to take you back to the main text).
This is meant as a service to those who read this talk on the screen.
In general, for getting started with the qDGCA technology which the computations are based on, the inclined reader should please take a look at the first part of our Zoo of Lie $n$algebras . This summarizes everything that is needed. Further literature is referenced.

Re: String and ChernSimons Lie 3Algebras
A couple minor comments on your slides:

You write ‘Jacoby’ one place where you mean ‘Jacobi’.

You write ‘Gray category’ where you mean ‘Graycategory’. The point here is that Gray is a monoidal category, and for any monoidal category $V$ people call a category enriched over $V$ a ‘$V$category’. I don’t insist on the boldface, but I insist on the hyphen!
Okay… now, the important part: could you say a little about the best way to get rom the airport to Pension ANI at Kinderspitalgasse 1, 9th district? Is it hard to get from the airport to the Alser Strasse UBahn stop?
Also: if you give me your room number (perhaps by email) I can give you a knock when I arrive. With luck, my flight may arrive at 18:10 on Saturday the 18th despite the demonstrations at Heathrow. I’d be interested in going out to dinner if that sounds fun. I can promise Claudia that I’m able to discuss subjects other than math and physics — but alas, only in English. If you’d prefer to meet sometime on Sunday, that would be great too.
