# Joris van Hoboken's thesis on Platonic solids,Kleinian singularities and ADE

1. Nov 4, 2006

### John Baez

In "week182", back in 2002, I referred to this very nice thesis:

Joris van Hoboken, Platonic solids, binary polyhedral groups, Kleinian
singularities and Lie algebras of type A,D,E, Master's Thesis, University of
Amsterdam, 2002, available at
http://www.science.uva.nl/research/math/Onderwijs/examen/2002/scriptiejoris.ps

Now I'm studying this stuff again. There are cool relations to ALE
spaces and string theory, and lots more.

Alas, I didn't keep a copy! It seems to be gone. James Dolan and
I can't find it using Google or the "wayback" web archive. I can't
locate van Hoboken, either.

Does anyone have a copy, please?

This is another reason people should put their theses on the arXiv!
Universities should also keep electronic copies of theses in some
publicly available electronic form.

Hello John Baez
Is this the paper you're looking for?

Got it! Excellent! Sam Wormley gave me a copy, and I'll make it
available here:

It's a nice description of some incredibly cool stuff. Check it out!

Its on the same set of servers, just moved around a bit.

Google scholar lists 4 different versions. The second gets you there.

I was able to pull it off the wayback machine just fine. Here's a
copy:

Looks neat. And I certainly agree with you on arxiving theses. They
often make great reading, as you get a youthfull perspective on issues.

Joris van Hoboken's thesis in mathematics

I got hinted by my former professor Koornwinder of the University of Amsterdam that my thesis (Platonic Solids, Binary Polyhedral Groups, Kleinian Sigularities and Lie Algebras of Type A,D,E) is a little hard to find. I started a blog several moths ago and made a post there, so it will be easy to find:
