    Séminaire Math-Phys : Global Existence, Blowup and Scattering for large data Supercritical and other wave equations

    Résumé : First, I will review the problem off Global existence for dispersive equations.
    Then, I present a new approach to classify the asymptotic behavior of certain classes of wave equations, supercritical and others, with large initial data. In some cases, as for Nirenberg type equations, a fairly complete classification of the solutions (finite time blowup or global existence and scattering) is proved.
    I will also present a new class of (quasi-normed) spaces that allow the extension of Global existence results for "large" data in the standard critical norms.
