Conférence en l’honneur de Emmanuel Rio : Concentré de martingales et mélange de chaînes de Markov

From wednesday June 11 to friday June 13,

to honor Emmanuel Rio’s outstanding career and his remarkable contributions to mathematics, a three-day event will be held in Versailles from June 11 to 13, 2025. His research on weakly dependent processes, concentration inequalities and their applications has influenced modern probability theory and statistics. The conference will bring together collaborators, former students, and leading experts to celebrate his exceptional achievements.

 

Organisateurs : Jérôme Dedecker (Université Paris Cité); Sana Louhichi (Université Grenoble-Alpes); Ester Mariucci (UVSQ); Florence Merlevède (Université Gustave Eiffel).

Programme

All talks will take place in Amphi H of the Fermat building, while coffee breaks and lunches will be set up in the adjacent room, Amphi I.
