On Discontinuous Galerkin Methods for Singularly Perturbed and Incompressible Miscible Displacement Problems [PDF]
, 2012 This thesis is concerned with the numerical approximation of problems of fluid flow, in particular the stationary advection diffusion reaction equations and the time dependent, coupled equations of incompressible miscible displacement in a porous medium.

Forme normale de Birkhoff en faible régularité
This thesis is devoted to the study of the long time behavior of small solutions of semi-linear non-resonant Hamiltonian PDEs in low regularity. Many results were realised to prove long time stability in high regular- ity (in the Sobolev space Hs with s ...

Fractional and Integer Order Sobolev Spaces for Compact Metric Graphs [PDF]
Given a compact metric graph $Γ$ and the Laplacian $Δ_Γ$ coupled with standard (Kirchhoff) vertex conditions, solutions to fractional elliptic partial differential equations of the form $(κ^2 - Δ_Γ)^{α/2}u=f$ on $Γ$ exhibit a distinctive regularity ...

Birkhoff normal form in low regularity
Cette thèse est consacrée à l’étude du comportement en temps longs des pe- tites solutions des EDPs hamiltoniennes semi- linéaires non résonnantes en faible régularité. De nombreux résultats ont été réalisés pour montrer la stabilité en haute régularité (

Long time behavior of wave and plate equations [PDF]
Long time behavior of a class of nonlinear hyperbolic dynamics governed by Partial Differential Equations [PDEs] is considered in this thesis. The objective is to demonstrate that the long-term behavior can be directed towards coherent structures, such ...
