发帖数: 644 | 1 The 2012 SASTRA Ramanujan Prize will be awarded to Professor Zhiwei Yun,
who has just completed a C. L. E. Moore Instructorship at the Massachusetts
Institute of Technology and will be taking up a faculty position at
Stanford
University in California this fall. The SASTRA Ramanujan Prize was
established
in 2005 and is awarded annually for outstanding contributions by very young
mathematicians to areas influenced by the genius Srinivasa Ramanujan. The
age limit for the prize has been set at 32 because Ramanujan achieved so
much in his brief life of 32 years. Because 2012 is the 125th anniversary
of the birth of Srinivasa Ramanujan, the prize will be given in New Delhi
(India’s capital) on December 22 (Ramanujan’s birthday), during the
concluding
ceremony of the International Conference on the Legacy of Ramanujan
conducted
by the National Board of Higher Mathematics of India and co-sponsored by
SASTRA University and Delhi University. Dr. Yun will also be invited to
speak at the International Conference during December 14–16 at SASTRA
University
in Kumbakonam (Ramanujan’s hometown) where the prize has been given
annually
in previous years.
Dr. Zhiwei Yun has made fundamental contributions to several areas that lie
at the interface of representation theory, algebraic geometry and number
theory.
Yun’s PhD thesis on global Springer theory at Princeton University, written
under the direction of Professor Robert MacPherson of The Institute for
Advanced Study, is opening up whole new vistas in the Langlands program,
which represents one of the greatest developments in mathematics in the last
half-century. Springer theory is the study of Weyl group actions on the
cohomology of certain subvarieties of the flag manifold called Springer
fibers. Yun’s global Springer theory deals with Hitchin fibers instead of
Springer fibers (taking the lead from earlier work on Hitchin fibers by
Gerard Laumon and the 2010 Fields Medalist Bao-Chau Ngo) which
he uses to determine the actions of affine Weyl groups on cohomolgy. His
work is expected to lead to a geometric and functorial understanding of
the Langlands program. Many papers by him on global Springer theory have
arisen from his PhD thesis; one has appeared in 2011 in Advances in
Mathematics
and another will soon appear in Compositio Mathematica.
Bao-Chau Ngo was awarded the 2010 Fields Medal for his proof of the
Fundamental
Lemma in the Langlands Program. Yun has made a major breakthrough in the
study of the Fundamental Lemma formulated by Jacquet and Rallis in their
program of proving the Gross–Prasad conjecture on relative trace formulas
. Yun’s understanding of Hitchin fibrations enabled him to reduce the
Jacquet
–Rallis fundamental lemma to a cohomological property of the Hitchin
fibration
. This work, considered a gem of mathematics, appeared in 2011 in the Duke
Mathematical Journal.
Yun has collaborated with Ngo and Jochen Heinloth on a seminal paper
on Klooster- man sheaves for reductive groups which will appear in the
Annals
of Mathematics. In this wonderful joint paper, Ngo, Heinloth and Yun
reprove a unicity result of Gross on auto- morphic representations over
the rational function field, and use the geometric Langlands theory to the
construction of l-adic local systems.
Yun has also done significant work in algebraic geometry. His recent article
with Davesh Maulik on the Macdonald formula for curves with planar
singularities
will appear in The Journal fu¨r die Reine und Angewandte Mathematik. Yun
’s most recent work on the uniform construction of motives with exceptional
Galois groups is considered to be a fundamental breakthrough. A
construction
like Yun’s was sought by Fields Medalists Serre and Grothendieck for over
40 years, and Yun’s work is considered one of the most exciting
developments
in the theory of motives in the last two decades.
Zhiwei Yun was born in Changzhou, China in 1982. He showed his flair for
mathemat- ics early by winning the Gold Medal in the 41st Mathematical
Olympiad
in 2000 in Korea. He joined Peking University in 2000 on a Ming-De
Fellowship
and obtained a bachelor’s degree there in 2004. He continued his studies
at Princeton University, where he received his PhD in 2009. He was Visiting
Member at the Institute for Advanced Study in 2009–10, and held the C.L
. E. Moore instructorship at MIT during 2010–12. In fall 2012, he will join
the mathematics faculty at Stanford University. At the age of 30, he has
established himself as one of the young leaders of modern mathematics.
The international panel of experts who formed the 2012 Prize Committee were
University
of Utrecht; Kathrin Bringmann, University of Cologne; Benedict Gross,
Harvard
University; Kenneth Ribet, University of California, Berkeley; Robert
Vaughan
, The Pennsylvania State University; Ole Warnaar, University of Melbourne
.
Previous winners of the SASTRA Ramanujan Prize include Manjul Bhargava and
Kannan Soundararajan in 2005 (two full prizes), Terence Tao in 2006, Ben
Green in 2007, Akshay Venkatesh in 2008, Kathrin Bringmann in 2009, Wei
Zhang in 2010 and Roman Holowinsky in 2011. Thus Zhiwei Yun joins an
impressive
list of brilliant mathematicians who have made monumental contributions
at a very young age. | l********e
