I’ll see you in Vienna!
Am looking forward to it!
Im staying at the Pension ANI
Yes, so am I. I arrived already last Saturday, spending the weekend with Claudia here in Vienna.
I thought maybe I’d warn you: first time I was in Vienna I stayed in “Kaiser Franz Joseph”. The difference between the two places is pretty much what the difference in their names suggests. Pension Ani is a very simple place. It’s clean and all, but – simple.
We arrived late at night and were let in by a funny guy who seemed to have been left over from the penultimate century. He began or/and ended each of his sentences dead seriously with “dear Mr. Doctor”. No joke! I didn’t know how irritating this can be.
So be prepared. No telling what happens when he runs into a professor! :-)
Do you know when you’re giving your talk?
Tomorrow already, Tuesday 14th.
I don’t see you on this schedule,
I am on the other schedule! :-)
Too bad your talk isn’t right after that: I’m talking about Lie 2-algebras, while you’re doing Lie 3-algebras!
Yes, I know. The two talks would fit nicely together, in fact.
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 Chern-Simons Lie 3-Algebras )
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 -algebras . This summarizes everything that is needed. Further literature is referenced.
A couple minor comments on your slides:
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 U-Bahn 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.
A couple minor comments on your slides:
Thanks! Fixed version is now available.
the best way to get from the airport to Pension ANI
There are, I think, two main possibilities to get from the airport into the city: the slow and cheap option is to take the ordinary train, the other is to take what is called the CAT (City Airport Train).
You need to change one or two times then to different subways.
Here is the map of the subway and “S-Bahn” system.
Finally, take the subway U6 and get off at station Alser Strasse. The hotel is just a few meters from there.
I’ll prepare a Google Map for you with all the details in about an hour, when the first talk is over.
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.
Yes, let’s do that.
Claudia left this morning, in fact, and I will change from a double room to a single room tomorrow morning. Therefore I actually cannot tell you right now which room number I’ll be in.
My mobile phone number is
+49 (0)152 0858 1866
If everything fails, we could simply agree to meet at, let’s see, 20:30 or so in the hotel lobby.
Thanks! When I show up, I’ll try to find out which room you’re in. If you’re not in yet, or I fail to find you, let’s try to meet in the lobby at 20:30.
Here is now a quick GoogleMap into which I entered some hopefully useful information.
I am a bit in a hurry. Maybe check the link again later. I’ll try to improve the information a little more.
Re: String and Chern-Simons Lie 3-Algebras
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 sigma-models” 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 2-algebras, while you’re doing Lie 3-algebras!
