“Partial Differential Equations, Analysis and Geometry”, A Conference in Honor of Sergiu Klainerman’s 75th Birthday

Sergiu Klainerman, mathematician at Princeton University, best known for his contributions to the study of hyperbolic differential equations and general relativity, celebrated his 75th birthday in May of this year. In his honor, Elena Giorgi (Columbia University), Markus Keel (University of Minnesota), Jérémie Szeftel (Sorbonne Université) organize a one-week conference from January 12 to 16, 2026.

The event will bring together experts to present recent advances in analysis, PDE, geometry, and general relativity, with the aim of fostering interaction across fields and engaging early-career researchers in these exciting developments.

Invited Speakers:

• Scott Armstrong (Sorbonne Université)
• Demetrios Christodoulou (ETH Zürich)
• Thibault Damour (IHES)
• Camillo De Lellis (IAS)
