Grothendieck’s survival talks
on August 6, 2009 by lieven in general, lazy blogging, Comments (2)
The Grothendieck circle is a great resource to find published as well as unpublished texts by Alexander Grothendieck.
One of the text I was unaware of is his Introduction to Functorial Algebraic Geometry, a set of notes written up by Federico Gaeta based on tape-recordings (!) of an 100-hour course given by Grothendieck in Buffalo, NY [...]
Gina says (continued)
on August 5, 2009 by lieven in general, lazy blogging, Comments (1)
Via the Arcadian functor I’ve grabbed the full text of Gil Kalai’s book Gina Says: Adventures in the Blogsphere String War (part 1 and part 2) and read it on a lazy sunny afternoon.
Arguably the best paragraph is the final one, and, it might be sensible to start the book by reading it first [...]
Now here’s an idea

Boy, do I feel stupid for having written close to 500 blog-posts hoping (in vain) they might eventually converge into a book project…
Gil Kalai is infinitely smarter. Get a fake gmail account, invent a fictitious character and start COMMENTING and provoking responses. That’s how “Gina” appeared on the scene, cut and pasted her comments (and [...]
noncommutative space quiz
on May 21, 2009 by lieven in geometry, lazy blogging, Comments (4)
Creating (or taking) an image and explaining how it depicts your mental picture of a noncommutative space is one thing. Ideally, the image should be strong enough so that other people familiar with it might have a reasonable guess what you attempt to depict.
But, is there already enough concordance in our views of noncommutative spaces? [...]
Pollock your own noncommutative space
on May 19, 2009 by lieven in geometry, lazy blogging, Comments (4)
I really like Matilde Marcolli’s idea to use some of Jackson Pollock’s paintings as metaphors for noncommutative spaces. In her talk she used this painting
and refered to it (as did I in my post) as : Jackson Pollock “Untitled N.3”. Before someone writes a post ‘The Pollock noncommutative space hoax’ (similar to my own post) [...]
Views of noncommutative spaces
on May 18, 2009 by lieven in geometry, lazy blogging, Comments (3)
The general public expects pictures from geometers, even from non-commutative geometers. Hence, it is important for researchers in this topic to make an attempt to convey the mental picture they have of their favourite noncommutative space, … somehow. Two examples :
This picture was created by Shahn Majid. It appears on his visions of noncommutative geometry [...]
lazy weekend blogging (1) : after Kronecker’s

“Die ganzen Zahlen hat der liebe Gott gemacht, alles andere ist Menschenwerk.”
and after the original from Abstruse Goose.
Hi, I'm a professor of mathematics at the University of Antwerp, in Belgium. My research areas are non-commutative algebra and non-commutative geometry. Sometimes, you can also find me here :
