Friends of IHES and IHES organized an online event on April 22, 2021 at 12.00 pm EST. On this occasion, Sergiu Klainerman gave a talk on “Are Black Holes Real? A Mathematics perspective”.

Sergiu Klainerman is the Eugene Higgins Professor of Mathematics at Princeton University. He is a Partial Differential Equations analyst with a strong interest in General Relativity. His research deals with the mathematical theory of black holes, more precisely on their rigidity and stability. He is also interested in the dynamic formation of trapped surfaces and singularities. Recently, in collaboration with Jeremie Szeftel, Klainerman has published a book in Princeton University Press which establishes the first nonlinear stability result for the Schwarzschild black holes for general polarized perturbations.

He has received several awards including the Bôcher Memorial Prize by the American Mathematical Society, the MacArthur Fellowship and the Guggenheim Fellowship.

Klainerman is a member of the U.S. National Academy of Sciences, a foreign member of the French Academy of Sciences, Fellow of the American Academy of Arts and Sciences and, he was recently elected Fellow of the American Mathematical Society.

He was the co-Editor-in-Chief of Publications mathématiques de l’IHES and is currently a member of Friends of IHES.

Slava RYCHKOV‘s conference, “Contre la logique du Lego“, organized by Les Amis de l’IHES, was initially scheduled to take place in person at IHES on Thursday, March 12, 2020. Following the global health crisis, the conference was postponed and took place online on Zoom on October 29, 2020, from 5:30 pm to 7:00 pm.

Abstract:

“Traditional physics wants to find elementary constituents in each phenomenon, which are assembled like Lego bricks to build more complicated objects. I want to imagine with you another world, or another physics, which does not use elementary components“.
