Talk:Daniel Quillen

message: User:128.135.227.154 removed the sentence "Amongst his collaborating mathematicians is his former PhD student Mathai Varghese", with the comment: "Removed reference to Mathai. The wrote one (not very important) paper together in the 1980's. Quillen has written many papers with a variety of coauthors."  I do not see this as justified.  First of all, yes, Quillen wrote many papers, with several coauthors (not that many of them, actually), but, as far as I know, the paper with Mathai (Superconnections, Thom classes, and equivariant differential forms, Topology, 1986) is the only one he wrote with one of his PhD students, and this is a good way to bring that aspect of Quillen's career in.  And second, I also disagree with the assessment that that is not a "very important" paper: not among the very top papers of Quillen, to be sure, but quite a significant paper, nonetheless -- the basis for the "Mathai-Quillen formalism", it is listed on MathSciNet  with 39 quotations from articles and 18 from reviews (which is quite a bit), while on Google Scholar it registers 161 citations (which is really a lot for a math paper).

replies: text: I fully agree, the article is far from finished -- it should be rated somewhere between a Stub and a Start -- and important information is still missing, for example, the paper on "Rational Homotopy Theory", which must rank among the top 10 most influential papers in Algebraic Topology, ever.  But that's the idea of wikipedia -- one starts small, and builds up the article, with input from many editors. Deleting stuff because the perfect pitch has not yet been reached is not quite the way to go. Much better is to add content to the article, and, if an issue like this arises, talk about it first on the Talk page (like we're doing now) before taking drastic action. At any rate, this is one of the articles I plan to work on more when I get a chance, I will see what I can do.  Turgidson 15:08, 18 March 2007 (UTC)
replies: text:  Fair enough.  I've done a rearrangement of the Quillen page and restored the reference to Mathai in a more appropriate context (a list of students).  I've also added references to the theory of model categories and rational homotopy theory.  Someone (perhaps me when I have a large block of free time, but I'm in the midst of writing several long papers right now, so it won't be soon) should expand each of the entries in the "Selected Mathematical Contributions" into a separate section. 128.135.227.91 16:31, 18 March 2007 (UTC)
replies: text: Looking good.  I'll add a selected list of papers when I get a chance -- basically the ones mentioned implicitly in the text, plus a few others (eg, the one in J. Algebra about the associated graded ring of a group ring, which I think is a little gem, also quite influential).  Turgidson 16:42, 18 March 2007 (UTC)
