New Research from Professor Sergiu Klainerman
Sergiu Klainerman, Professor of Mathematics at Princeton University and faculty associate of the James Madison Program, is a co-author of new pathbreaking work on the stability of Kerr black holes. Kerr black holes, which are rotating black holes, were first theorized by mathematician Roy Kerr in the 1960s as a solution for Einstein's equations in the general theory of relativity.
Professor Klainerman and his co-authors, Jérémie Szeftel at Sorbonne University, and Elena Giorgi of Columbia University, created a proof by contradiction to show that Kerr black holes are stable. This proof is critical, because if Kerr black holes were unstable that would require a revision to Einstein's theory of gravitation. Steve Nadis, in an article for Quanta Magazine, reports that mathematicians see this new proof as an important milestone. Klainerman, Nadis writes, considers the latest paper a collective achievement, resting on decades of research by other mathematicians. Klainerman would like the new contribution to be viewed as “a triumph for the whole field.”
The James Madison Program congratulates Professor Klainerman and his colleagues on this important contribution to mathematics research! Check out the December 2020 episode of Madison's Notes to learn more about Professor Klainerman and his experiences growing up in communist Romania.
