Since its creation in 2001, the "Chaire de la Vallée Poussin" is awarded every year to a world-renowned mathematician. It is held in the form of a 4-day-series of lectures with international public. (Outside of pandemics, they take place at Louvain-la-Neuve in the lecture hall that carries the same name as the memorial prize.) An inaugural lecture on the first day is followed by 3 more lectures, exploring the topic in some more depth.

The chaire de la Vallée Poussin is named after Charles de la Vallée Poussin, one of the greatest Belgian mathematicians. He was professor at Université catholique de Louvain between 1891 and 1962.

The prize lectures 2020/21 will start on 14/12/2021. The laureate is **Guido De Philippis** (New York University).

The general title for his set of lectures will be **"PDE constrained inclusions"**

The **inaugural lecture** will be held **14/12/2021, 16h15 - 17h15 on zoom.**
