From the International Mathematical Union:
"Martin Hairer has made a major breakthrough in the study of stochastic partial differential equations by creating a new theory that provides tools for attacking problems that up to now had seemed impenetrable…
…Some of the most important natural phenomena are governed by nonlinear PDEs, so understanding these equations is a major goal for mathematics and the sciences. However, nonlinear PDEs are among the most difficult mathematical objects to understand. Hairer’s work has caused a great deal of excitement because it develops a general theory that can be applied to a large class of nonlinear stochastic PDEs."
