Global Existence, Blowup and Scattering for large data Supercritical and other wave equations

Monday, October 3, 2016 -
3:00pm to 4:30pm
PLEASE NOTE NEW START TIME OF 3:00.   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. New results are obtained for the well known monomials wave equations in the sub, critical and super critical cases. This approach, developed jointly with M. Beceanu, is based on a new decomposition into incoming and outgoing waves for the wave equation, and the positivity of  the fundamental solution of the wave equation in three dimensions.
