Hello, I am at the Ecole Polytechnique . If you want to reach me, send me e-mail or regular mail

Ilan Vardi, Departement d'Informatique, Ecole Polytechnique, 91128 Palaiseau, France.

If I'm not here, then I am probably elsewhere with my foxy wife.

I have written papers (see the math reviews and what Science News has to say) on a number of different subjects. See my resume (in postscript ).

I am an editor of Advances in Applied Mathematics , and you can submit articles to me directly.


I have typeset Field medalist Paul J. Cohen's 1958 Ph.D. thesis Topics in the theory of uniqueness of trigonometrical series . This work was previously only available at the University of Chicago library. Though Paul Cohen is best known for his groundbreaking work in set theory, he also had many important contributions in harmonic analysis starting with his thesis which is still relevant to current research in this area. I have included a brief summary and bibliography of subsequent work in this area.

When I was a kid, all I did was play chess. This is me losing to future grandmaster Kevin Spraggett in the final round of the 1975 Montreal Open (but hey, I tied for first).

I gave a lecture at a special mathematics day at the Centre Pompidou on September 18, 2000.

I have written an IHES visitor's guide and answers to some Frequently Asked Questions.

I have also just written a sightseeing guide to the region near the IHES.

I have just finished writing up a complete solution set to Mekh-mat entrance examination problems (or go directly to the postscript file). These consist of ``killer problems'' given to Jewish candidates to the Mek-mat in Moscow during the 1970's and 1980's. See the list of problems .

For comparison, I have also written up solutions to the year 2000 International Mathematical Olympiad, see the postscript file . Here are the questions .
