Nessim Sibony

Nessim Sibony was a French mathematician, specializing in the theory of several complex variables and complex dynamics in higher dimension. Since 1981, he was professor at the University of Paris-Sud in Orsay.

Biography

Sibony received in 1974 his PhD from the University of Paris-Sud with thesis Problèmes de prolongement analytique et d'approximation polynômiale pondérée. His research deals with complex analysis and complex dynamics in several variables, including collaboration with John Erik Fornæss and
Dinh Tien-Cuong on Fatou-Julia theory in several complex variables and on singular foliations by Riemann surfaces.
Independently of Adrien Douady and John H. Hubbard, Sibony proved in the 1980s that the Mandelbrot set is connected.
In 1985 he received the Vaillant Prize and in 2009 the Sophie Germain Prize from the French Academy of Sciences. For 2017 he received the Stefan Bergman Prize. In 1990 he was an Invited Speaker with talk Some recent results on weakly pseudoconvex domains at the ICM in Kyōto. He was a senior member of the Institut Universitaire de France from 2009 to 2014.
