SNCF engineers have been using mathematical models for many years to simulate the dynamic behavior of railways.

The CNRS and its Mexican partners, the National Autonomous University of Mexico (UNAM) and the National Council of Science and Technology (CONACYT), have just created an international joint unit (UMI) in mathematics, the "Laboratoire Solomon Lefschetz - LaSoL."

An international team (Cornell University, Hokkaido University, Max Planck Institute, Ecole normale supérieure de Lyon / Université Claude Bernard Lyon 1 / CNRS / INRA) unravels how random cell growth contributes to making organs reach the correct size and shape.

Tiling the plane with a single pattern is a mathematical problem that has interested humans since Antiquity, notably for the aesthetic quality of tiles in mosaics or tiling.

Mega-earthquakes (with a magnitude greater than 8.5) mainly occur on subduction faults where one tectonic plate passes under another.

In a recent paper published jointly in Inventiones Mathematicae and Mathematische Zeitschrift, Albert Fathi , mathematician for UMPA (and his coauthors Andrea Davini, Renato Iturriaga and Maxime Zavidovique revisit a fundamental result in homogenization theory, obtained in 1987 by Lions, Papanicolaou and Varadhan.
