Technion - Israel Institute of Technology Department of Mathematics ============================================ PDE AND APPLIED MATHEMATICS SEMINAR ============================================ DATE: Tuesday, May 3, 2011 SPEAKER: Vincenzo Vespri, Firenze TITLE: Harnack estimates for degenerate parabolic equations PLACE: Room 814, Amado Mathematics Building, Technion TIME: 14:30 Abstract: We consider p -Laplacian equations and porous medium equations and we speak how to extend the classical Moser's estimates to these classes of equations. We speak about recent contributions (togheter with E. DiBenedetto and U. Gianazza) on this topic. The novelty of this new appoach is that we use DeGiorgi's function spaces insetad of the celebrated cross-over lemma. As a byproduct we get a different proof of Moser's estimates and we have a new more geometric approach to prove the regularity of the solutions.
