The Clay Research Award was presented to Yves Benoist in 2011 for his progress on the stationary measures and closed orbits of group actions. A specialist in dynamical systems, he holds a position as a senior researcher at the CNRS, operating primarily out of the University of Paris-Sud.
Early Career and Theoretical Foundations
Benoist received his training at the École Normale Supérieure. His early contributions focused on the dynamics of groups within homogeneous spaces, a core interest that would define his later career. In 1990, he collaborated with Patrick Foulon and François Labourie to address an open conjecture concerning Anosov flows on compact, negatively curved manifolds.

Take the IQ test →Developments in Projective Geometry
During the 2000s, Benoist produced a substantial series of research papers centered on divisible convex sets located within projective space. His investigations during this period also explored periodic tilings constructed from these specific geometric sets, documented in several publications from 2001 to 2006, including studies on three-dimensional boundary structures.
Collaborative Research and Recognition
His partnership with Jean-François Quint resulted in significant advancements in the field, specifically concerning the equidistribution of orbits of Zariski dense subgroups. By solving a long-standing conjecture originally proposed by Hillel Furstenberg, the pair demonstrated how these orbits distribute toward algebraic measures in homogeneous spaces of finite volume. This work was a primary component of his 2011 Clay Research Award.
Professional Impact
Benoist continues to contribute to the mathematical community through lectures and seminars. In 2012, he delivered the Takagi Lectures at the Research Institute for Mathematical Sciences in Kyoto. He further disseminated his findings as an invited speaker at the 2014 International Congress of Mathematicians held in Seoul.
