SUMMARY:Seminar in Numerical Analysis: Omar Lakkis (University of Sussex)
DESCRIPTION:Aposteriori error analysis for Galerkin finite element methods 
 have proven very successful tool in developing mathematically rigorous ada
 ptive mesh refinement algorithms for implicit/space-time evolution equatio
 ns. In this work we extend rigorous adaptivity principles to explicit time
 -stepping for the wave equation.\\r\\nI will review in the first part of t
 he talk the state of the art for the wave equation. In the second part\, I
  will present recent work in connection to fully practical explicit scheme
 s such as the Leapfrog method and local time step variants thereof.\\r\\nT
 his talk is mostly based on recent joint work with M Grote\, C Santos and 
 earlier work with EH Georgoulis\, C Makridakis and J Virtanen.\\r\\nFor fu
