Pablo Rotondo has obtained a permanent position as maître de conférences (assistant professor) at the Université Gustave Eiffel, from September 2021

Wed, 16 Jun 2021 23:40:37 +0000

Philippe Flajolet, computer scientist and mathematician. Member of the Academy of Sciences, left us ten years ago, on March 22, 2011.

Sun, 21 Mar 2021 14:15:55 +0000

All of us, who work in the fields of mathematical informatics, in France and abroad, we will not forget him.
Philippe’s work accompanies us every day in our research and shows us the way.

Several members of SINFIN, notably in the ”Randomness and Analysis of Algorithms” team, worked hand by hand with Philippe Flajolet.
