Federico Cacciafesta (IHP): "Endpoint Strichartz estimates and the cubic nonlinear Dirac equation"
Wednesday 15 May 2013, 15:30 - 16:30
Amphi Darboux


Abstract: In this talk I will present some recent results obtained in collaboration with P. D'Ancona concerning global wellposedness for a critical nonlinear Dirac equation with a potential, the main tool being given by some refined endpoint Strichartz estimates. After recalling the general framework when dealing with low regularity problems, I will show how significant improvements can be achieved on dispersive estimates when requiring some additional angular regularity on the initial data.
