The Centre de recherches mathématiques (CRM) hereby solicits nominations for the André-Aisenstadt Mathematics Prize awarded to recognize talented young Canadian mathematicians.

The André-Aisenstadt Mathematics Prize, which is given for research achievement in pure and applied mathematics, consists of a $ 3 000 award and a medal.

The recipient is chosen by CRM's advisory committee. The prize is generally awarded yearly, although in a given year the decision may be made not to award it.

At the time of consideration, candidates must be Canadian citizens or permanent residents of Canada, and no more than seven years from their Ph.D.

A condition of acceptance of the prize is that recipient deliver a lecture at CRM, at a time mutually agreed upon. Also, a brief description of the work is to be prepared by the recipient for publication in the CRM Bulletin.

Nominations must be submitted by October 1, 2005 to the Director of the CRM, by at least two sponsors who are responsible for providing the following information:

  • curriculum vitae
  • publication list
  • covering letter explaining the basis of the nomination
  • up to four prints
  • a maximum of four letters of support

    Unsuccessful nominations remain active for two further years if not withdrawn and if the rule regarding the completion of the Ph.D. within seven years is still satisfied. The nominations can be updated if desired.

    Created in 1991, the André-Aisenstadt Mathematics Prize is intended to recognize and reward research achievements in pure and applied mathematics by talented young Canadian mathematicians. Previous recipients of the André-Aisensadt Prize: Niky Kamran (1991), Ian Putnam (1992), Michael Ward et Nigel Higson (1994), Adrian S. Lewis (1995), Lisa Jeffrey and Henri Darmon [1996), Boris Khesin (1997), John Toth(1998) et Chanfeng Gui (1999), Eckhard Meinrenken (2000), Jinyi Chen (2001), Alexander Brudnyi (2002) and Vinayak Vatsal (2003) .



The 1997 André-Aisenstadt Mathematics Prize was awarded to Professor Boris A. KHESIN of the University of Toronto.

HIS WORK: Professor Khesin was cited for his work in infinite-dimensional Poisson geometry and Lie groups and his wonderful geometric intuition applied to problems in topological hydrodynamics and groups of double loops. He did fundamental work in bifurcation theory where he proved R. Thom's rule of "seven elementary catastrophes" in dynamical systems. Professor Khesin also discovered the "logarithm of the derivative," a beautifully simple notion providing a link between determinant theory and the theory of infinite-dimensional integrable systems.

HIS STUDIES AND AFFILIATIONS: Boris Khesin did his undergraduate and graduate work at Moscow State University, obtaining his Ph.D. under the direction of Professor V. I. Arnold in 1990. He then held positions at the University of California at Berkeley, Yale University and the Isaac Newton Institute before accepting a permanent position at the University of Toronto where he is currently an associate professor and Sloan Fellow.

Professor Khesin presented a lecture at the CRM in January 1998.



The CRM Advisory Committee recommended the awarding of two André-Aisenstadt Prizes for the academic year 1996-97. These went to Henri Darmon and Lisa Jeffrey, both of McGill University.

Henri DARMON (McGill University)
HIS WORK: Henri Darmon was cited for his remarkable work in the area of elliptic curves, particularly for his refinements of the famous Birch Swinnerton-Dyer conjecture. He has also made significant contributions to research on variants of the Fermat equation. In addition to his superb research contributions, Professor Darmon is a splendid expositor and a recent paper explaining the subtleties of Wiles' work on the Shimura-Taniyama conjecture has been widely celebrated.
Professor Darmon obtained his B.Sc. in Mathematics and Computer Science at McGill University in 1987 and his Ph.D. in Mathematics at Harvard University in 1991. He then spent 4 years at Princeton University before coming to McGill University where he is currently an associate professor.
He has also held various visiting positions at such institutions as ETH in Zurich, the Mathematical Sciences Research Institute in Berkeley, and IHES in Paris. Henri Darmon has published more than 26 research papers and won numerous awards, among them an Alfred P. Sloan Doctoral Dissertation Fellowship and an Alfred P. Sloan Research Award.

Lisa C. JEFFREY (University of Toronto)

HER WORK: Lisa Jeffrey was awarded the André-Aisenstadt Prize for her distinguished research contributions in Symplectic Geometry and various aspects of the relation between Topology and Physics. In particular, in joint work with Frances Kirwan, she obtained a complete description of the cohomology ring of the moduli space of vector bundles on a Riemann surface solving an important conjecture of Witten. Techniques invented in the course of this work have proved useful in solving other significant problems as well.

Professor Jeffrey obtained the A.B. at Princeton University, the M.A. at Cambridge University and the Ph.D. at Oxford University in 1992 under the direction of M.F. Atiyah. She then held positions at the Institute for Advanced Study, Cambridge University, and Princeton University before coming to McGill University in 1995 where she is currently Associate Professor of Mathematics. Professor Jeffrey has written over 21 research papers and numerous review articles. Among the honors she has received are the Kusaka Memorial Prize in Physics from Princeton University and the Smith Prize from Cambridge University.

The two André-Aisenstadt prize winners gave lectures on their work at the CRM on February 28, 1997. Professor Darmon's lecture was entitled "Faltings plus epsilon et l'équation de Fermat généralisée" and Professor Jeffrey's was entitled "Flat connections on Riemann surfaces."

Adrian S. LEWIS

The André-Aisenstadt Mathematics Prize for 1995 was awarded to Professor Adrian S. LEWIS of the University of Waterloo. Professor Lewis was cited for his deep contributions in a wide range of mathematical areas: mathematical optimization, convex and nonsmooth analysis, functional analysis, matrix theory, and computational optimization. In particular he is world renowned for his work in the field of convex programming of Hermitian matrices. The prize was awarded on April 26, 1996 at the CRM by Luc Vinet, director, following a lecture by Professor Lewis entitled "Convex Analysis and Applications."

HIS WORK: Adrian Lewis has published more than 30 articles in prestigious refereed journals and has given numerous invited presentations and colloquia, among them a keynote speech at the SIAM Conference on Optimization in 1996. He has also accepted invitations to Marseilles and Toulouse for joint research and expositions of his work. He is a member of the editorial board of the SIAM Journal on Optimization, and referees and reviews for ten other important journals.

HIS STUDIES AND AFFILIATIONS: Professor Lewis did his undergraduate and graduate studies at Cambridge University in England, obtaining his Ph.D. in 1987. His thesis was entitled "Extreme point methods for infinite linear programming." After research fellowships at Cambridge University and Dalhousie University he moved to the University of Waterloo in 1988 where he is currently Associate Professor in the Department of Combinatorics and Optimization.
