http://www.ens-lyon.fr/~dlouapre/ home page has a CV also a link to some funky music and a card for French "buzzword bingo" I am finding as I go along that the newest work in quantum gravity is being done by virtual children from my (perhaps too old) perspective edit: I see that Louapre was born in 1978 The cry of "Bingo" in French is apparently "Foutaise" which sounds slightly racy to me even Rovelli, at marseilles, who has the written the book on current efforts to quantize GR, looks to be rather young from his photo----35 at most I'd guess--- and he's one of the senior people Anyway Louapre has come up with interesting ideas vis-a-vis the "assymptotic 10j" obstacle which Baez identified one year ago in some papers he and some others wrote circa September 2002 ( mentioned a few days ago in TWF #198). So I will try to get some links to a David Louapre paper or two. And then as Baez said there will be a conference on spin foams in Spring 2004 in marseilles and Louapre (does he even have his PhD yet?) is one of the organizers and we will see what he says there. But in the meantime I will post what I can find in this thread edit: Here is one from December of last year http://arxiv.org/abs/gr-qc/0212001 "Diffeomorphisms and spin foam models"
