This Is Not The n-Category Café

April 24, 2014

The n-Category Café is located at http://golem.ph.utexas.edu/category. We only keep this site as a backup for the odd occasion when the main site goes down.

Main Site Temporarily Down

January 6, 2012

The n-Category Café is located at http://golem.ph.utexas.edu/category. We keep this site as a reserve in case anything goes wrong.

The main site will be temporarily down for 48 hours starting at 6pm Central Standard Time on Friday 6 January. In Greenwich Mean Time, that’s midnight at the end of 6 January and the beginning of 7 January. They’re shutting off the power to the building at the University of Texas where the server lives.

The Scottish Category Theory Seminar

May 5, 2010

The Scottish Category Theory Seminar is a newish series of occasional afternoon meetings, at locations roaming around the country (though there’ll probably never be any on highland mountaintops or remote misty lochs…). I’m very pleased to announce the second meeting of the seminar, in Edinburgh on 21 May.

We’ve worked hard to get a good mixture of mathematicians on the one hand, and theoretical computer scientists on the other. Two of the speakers, Antony Maciocia and Peter Kropholler, are mathematicians — Maciocia is in algebraic geometry, and Kropholler at the intersection of group theory and topology. The other two, Dirk Pattinson and Thorsten Altenkirch, are in theoretical computer science — though their talks should definitely be interesting to mathematicians.

All the speakers have been firmly requested to make their talks broadly accessible to what we hope will be a very mixed audience. So I’m looking forward to an excellent afternoon.

Here are the talks. To see the abstracts, click on the titles.

Incidentally, I think the Glasgow speaker has been inspired by some other talks in Glasgow…

If you think you’d like to come, send a mail to me (T.Leinster#maths,gla,ac,uk) or scotcats#cis,strath,ac,uk. It’s not essential that you do so — you can just turn up — but it would help, and you definitely should if you’re intending to come for dinner.

Hardware Problem

April 30, 2010

Golem, the computer on which the Cafe runs, has sadly passed away. A replacement should be up and running late next week – Jacques is working on it, for which we’re very grateful.

Until then, you can leave comments at the loose ends thread here.

Thanks again for your patience.

Update (6 May) The cafe is now visible again, but not fully operational. With any luck it will be working properly in a couple of days.

Normal Service is Resumed!

March 22, 2010

Thanks once more to the sterling work of Jacques Distler, the original Café is up and running again. So, please go there, rather than here, for all your mathematical, physical and philosophical needs.

The software problems seem to be mostly fixed. One or two people still find themselves unable to leave comments. If this happens to you, please tell me or one of the other hosts. We’ll post the comment for you and see if we can get the problem sorted out. (And if you just can’t wait to get that comment into cyberspace, you can put it at the loose ends entry at this site.)

Thanks for your patience.
