DESCRIPTION:Title: <a href="https://researchseminars.org/talk/cam/6/">On N
 itsche approach for a finite element scheme for Maxwell equations</a>\nby 
 Mohammad Asadzadeh (Chalmers & University of Gothenburg) as part of CAM se
 minar\n\nLecture held in MV:L14.\n\nAbstract\nWe show improved convergence
  for a $h-p$\, streamline diffusion (SD)\, Nitsche's scheme for the Vlasov
 -Maxwell (VM) system. The standard Galerkin for VM equations\, as 1st orde
 r hyperbolic\, suffers from the draw-back of poor convergence. We have imp
 roved this convergence rate using: \n\n(i) The SD method that adds artific
 ial diffusion to the system.\n\n(ii) The $h-p$ approach to gain adaptivity
  feature. \n\n(iii) Combined\, differentiated\, Maxwell equations to rende
 r the first order hyperbolic system to a second order hyperbolic equation 
 (not applicable to Vlasov part). \n\n(iv) Add of {\\sl symmetry} and {\\sl
  penalty} terms to reach final step of Nitsche's scheme.\n\nNumerical exam
 ples are justifying the theory.\n
