The differential equations and calculus of variations is at the heart of the research carried out within the analysis team which develop new methods, notably topological or variational, to prove the existence of solutions, to study the spaces of functions appearing in partial differential equations, to obtain new functional inequalities and to analyze the qualitative properties of the solutions Regularity, symmetry, asymptotic behavior…).
