Yves Benoist

Yves Benoist is a French mathematician, known for his work on group dynamics on homogeneous spaces. He is currently a Director of Research (Directeur de Recherche) of CNRS at the University of Paris-Sud.

In 1990 Benoist proved a long open conjecture with Patrick Foulon and François Labourie about Anosov flows on compact, negatively curved manifolds. In the 2000s he wrote a series of papers on the divisible convex sets in projective space and periodic tilings by such sets.

In 2011 he was awarded the Clay Research Award along with his former doctoral student, Jean-François Quint.[1] The prize citation highlighted their work on stationary measures and closed orbits for non-abelian group actions on homogeneous spaces, solving a long-standing conjecture of Hillel Furstenberg. They showed that in homogeneous spaces of finite volume, orbits of a Zariski dense subgroup of a semisimple group equidistribute towards algebraic measures.

He gave the 2012 Takagi Lectures[2] in Kyoto at the Research Institute for Mathematical Sciences (RIMS). In 2014 he was an Invited speaker at the International Congress of Mathematicians in Seoul.
