- Professor Codà Marques hired on a research chair -
October 2013-June 2014: Fernando Codà Marques is hired on a Bézout research chair. He is now full professor at Princeton University, and famous for having settled, with Neves, a series of conjectures in differential geometry, starting with the Willmore conjecture. He was a plenary speaker at the 2014 International Congress of Mathematicians. His visit had ...
- Visit of professor Léonid Pastur -
October 2013 : Professor L. Pastur visited both LAMA and LIGM in October 2013. Guédon, Pajor and Pastur finalized the work initialized during the Pastur’s first stay in 2012, concerning a central limit theorem for linear eigenvalue statistics of the sum of independent matrices of rank one. The corresponding paper has been published in a ...

- Visit of professor Mustapha JAZAR -
March 2013 : M. Jazar (Lebanese University) visited CERMICS in March 2013. He worked in collaboration with R. Monneau on the development of numerical methods to understand the phenomenon of seawater intrusion. The corresponding results have been published in SIAM J. on Appl. Math. in 2014.
- Visit of professor Leonid Pastur -
October 2013 : Professor L. Pastur visited LAMA in October 2012, and started a joint work with Guédon and Pajor on central limit theorem for linear statistics of the sum of rank one independent matrices rank one. Loubaton (LIGM) had also the opportunity to interact with L. Pastur on various topics such as the behaviour ...
- Visit of professor Zenghu Li -
September 2012 : Professor Zenghu Li (Beijing Normal University) visited J.-F. Delmas from 02/09/2012 to 01/10/2012. He gave a talk at the ANR A3 (PI J.-F. Delmas) workshop at CIRM (Marseille) during the first week of september. Then, he worked with J.-F. Delmas on the research programm of his PhD student Hongwei Bi on branching ...
- Visit of professor Antoine DEZA -
August 2012 : Antoine Deza (Mac Master University, Canada) visited CERMICS from July 1 to August 31. He worked in collaboration with F. Meunier and P. Sarabezolles (CERMICS) on a combinatorial approach to colourful simplicial depth conjecture. The conjecture has been verified in dimension 4, and the known lower bounds in higher dimensions have been ...
- Visit of professor Alejandro MAAS -
February – May 2012 : The professor Alejandro Maass (University of Chile) was invited by Bernard Host for four months from February to May 2012, two of which were financed by the Labex. This was a very fruitful visit. He gave a colloquium Math-info in Marne on “Rigidity results in cellular automata theory: probabilistic and ...
- Visit of professor Zoltan ESIK -
February 2012 : Zoltan Esik (Department of Computer Science, Szeged University) visited LIGM 1 month in February 2012. He initiated with Arnaud Carayol a work on the characterization of synchronizations trees definied by systems of functional equations. Together with Luca Aceto and Anna Ingólfsdóttir (School of Computer Science Reykjavik University), they obtained a full characterization ...
- Visit of professor Gabriele Steidl -
During the visit of Gabriele Steidl, new solutions for restoration problems involving images corrupted with Poisson noise have been devised. The idea is to employ an Anscombe based approximation which allows the variational problem to be formulated as a constrained convex optimization problem. The constraint is addressed through a novel epigraphical techniques and recent primal-dual ...
- Visit of professor Prasad TETALI -
Prasad Tetali (Georgia Institute of Technology, Atlanta) has been invited for a one month visit during the academic year 2011-2012. He worked with N. Gozlan, C. Roberto (Univ. Paris 10) and P.-M. Samson on optimal transport and its link with the Ricci curvature on discrete spaces. In Riemannian geometry, this subject attracted a lot of ...
