Laboratoire de Mathématiques d'Orsay (LMO)
Research unit
The research themes on which LMO focuses are varied and range from the most fundamental mathematics to the most applied ones. The lab is structured in 5 teams : Harmonic Research, Numerical Analysis and Partial Differential Equations, Arithmetics and Algebric Geometry, Probabilities and Statistics, Topology, and Dynamics and Geometry.
The mathematics studied at LMO allow the lab to cover varied application fields like health, biology, environment, aeronautics, automobile, safety, defense.... LMO also heavily interacts with entities like CEA, INRA, INRIA, INSERM ... As a part of several partnerships with the industry, LMO is a major actor in structuring the interface between mathematiciens and the industry : creation of the GDR CNRS Mathématiques et Entreprises in 2010, launched the concept of Semaine d'Etude Mathématiques et Entreprises, and participation in the AMIES LabEx.
