### The Scottish Category Theory Seminar

#### Posted by Tom Leinster

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 **Friday 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.

- Antony Maciocia (Edinburgh): Triangulated categories in algebraic geometry
- Thorsten Altenkirch (Nottingham): Monads need not be endofunctors
- Peter Kropholler (Glasgow): My favourite adjunctions
- Dirk Pattinson (Imperial): Category-theoretic proof theory of modal logics

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.

One may expect to see kilts I hope? (I actually have one)
