Parental visit

[pozorvlak]

Well, I survived the inspection, with only minor criticisms being levelled. In spite of the stress of the cleaning (which did take an entire week, though I didn't get much done on Wednesday or Thursday), it was nice to see my parents again. We went out for several nice meals, went for a walk by Loch Lomond (not as long as the ones I've been doing recently, hurrah!), went to the Kelvingrove Museum (rather busy, unfortunately), and played a game of Carcassonne (I came last, as per usual). And now they've gone up to Dundee for some nefarious reason known only to them.

Now I'm just worried about this play we're rehearsing in five days. The one that we still don't have scripts for. Well, I've got six hours on the train down to Cambridge on Friday afternoon, that should be enough...

Maths types: how well known would you say it is that limits and colimits in functor categories can be computed pointwise? I was in a lecture the other day where the lecturer painstakingly constructed pullbacks in G-Set (which is the same as [G, Set], and hence complete). I subsequently mentioned this to my (usually categorically ept) flatmate¹, who denied all knowledge. When I showed him the proof, he tried to cover by saying "Oh, you should have said you were computing them pointwise, I would have known what you were talking about then!". You're not fooling anyone, Philipp :-)

If you're looking for a hard core math(s) geek, I point you at stronae. I can point him here if you like.

Yes, please. Always good to know more mathematicians.

Also, hello and welcome!

As you can probably imagine, the whole thing with Phil Scott has left the situation in Cambridge a bit panicked. Script-writing was left for quite some time (even if she'd tried I doubt she would have been funny under the sort of strain) so we're a bit behind schedule on it. However, I've been assured that one will materialise before Friday, so don't fret on that account. Sorry, but like I said: the whole Phil Scott thing rather knocked us for six for a few days. Everything's always okay in Light Entertainment though!

Yeah, I know the reasons behind it, and under the circumstances I'm not criticising Gill at all. But it is getting rather close to rehearsal week.

On the other hand, I've been in enough Light Entertainment shows that I should be used to this kind of last-minute panic by now. I've told you about totherme's first show, right?

Hang on. Friday? I was planning to be down on Saturday night...
oh DEAR.
can you give me a ring and let me know?

I seem to recall having seen a proof of this "limits/colimits can be computed pointwise" in one of the references I skimmed during the last month. Can't, though, say where.

[pozorvlak.livejournal.com]

The proof's pretty straightforward: you write down the only definition possible and then check the relevant axioms. I TeXed it up, but unfortunately don't have access to it here. There's also a very short proof (about six lines) using ends. Unfortunately, unless you're familiar with ends, it's too slick to be really convincing!
