Benoit Pausader Universite' de Paris XIII Title: Global existence for the Euler-Maxwell 2 fluid system Abstract: The two fluid Euler-Maxwell equations is one of the fundamental system in plasma physics. It describes the behavior of two compressible fluids (ions and electrons) interacting through their self-induced electromagnetic field. We prove that a small smooth perturbation of a constant neutral equilibrium leads to a global solution that returns to equilibrium. These equations are time-reversible and the mechanism for control is through dispersion. In particular, a classical result of Sideris shows that this would be false in the absence of an electromagnetic field (compressible Euler develops shocks even from smooth small initial data). This is a joint work with Yan Guo (Brown) and Alexandru Ionescu (Princeton).Recording: http://mm.math.cmu.edu/recordings/cna/CNA-PausaderBenoit-Apr-02-2013.aviRecording: http://mm.math.cmu.edu/recordings/cna/CNA-PausaderBenoit-Apr-02-2013.mp4Date: Tuesday, April 2, 2013Time: 1:30 pmLocation: Wean Hall 7218Submitted by: David Kinderlehrer |
