 pressible Euler with physical vacuum: an Eulerian approach</a>\nby Daniel 
 Tataru (University of California Berkeley) as part of PDE seminar via Zoom
 \n\n\nAbstract\nThe compressible Euler equation  with physical vacuum is a
  free boundary problem in gas dynamics\, where the moving boundary represe
 nts the interface between gas and vacuum states\, with the density decayin
 g  to zero at the boundary. Such problems have been traditionally studied 
 using a Lagrangian approach and at high regularity. In this work we propos
 e a comprehensive alternative approach\, fully within the Eulerian setting
 \, and which leads to sharp results. This is joint work with Mihaela Ifrim
 \; the extension of these results to the relativistic case is also joint w
 ith Marcelo Disconzi.\n\nhttps://nguyenquochung1241.wixsite.com/qhung/post
