Prof. Yvon Maday had a visit to AMSS and gave a distinguished public lecture titled “Model Reduction Methods for Data Assimilation and for the Approximation of the Solution to Parameter Dependent PDE’s” at AMSS on 6, September, 2016.
In his speech, in order to construct physical or mechanical functional quantities such as fluid velocity, pressure field or concentration of some constituants…, one generally refers to two different approaches sketched as follows : i) the explicit construction based on data, ii) the implicit construction where, thanks to the understanding of the background phenomenon, a mathematical model is provided where the functional quantity of interest is solution of.
Yvon Maday is a professor in applied mathematics at the University Pierre et Marie Curie (Paris 6). He is also a member of Institut Universitaire de France (IUF), and a visiting professor at the Division of Applied Mathematics at Brown University. He won the Prix Blaise Pascal (GAMNI-SMAI) of the French Academy of Sciences in 1991 and the Prix Jacques-Louis Lions of the French Academy of Sciences in 2009. He has been a member of the European Academy of Sciences since 2003. He was an invited speaker in International Congress of Mathematicians 2006. He has been the director of the Laboratoire Jacques-Louis Lions from 2001 to 2011 and since then he has been invested in the development of collaborations with industrial partners, he is now the director of a “Carnot” structure that aims at increasing at a large scale the connections between academia and industries in applied mathematics.
