The 2006 Field Medalists have been announced:
Andrei Okounkov “for his contributions briding probability; representation theory and algebraic geometry.”
Grigori Perelman “for his contributions to geometry and his revolutionary insights into the analytical and geometric structure of the Ricci flow.”
Terence Tao “for his contributions to partial differential equations, combinatorics, harmonic analysis and additive number theory.”
Wendelin Werner “for his contributions to the development of stochastic Loewner evolution, the geometry of two-dimensional Brownian motion, and conformal field theory.”
As was widely predicted, Perelman declined his prize, and did not attend the ICM.
