SUMMARY:Nelder Fellow lecture series – Prof Ed Bueler (University of Alas
 ka Fairbanks)
DESCRIPTION:Prof Ed Bueler (University of Alaska Fairbanks): The mathematic
 al (and numerical) problem of glaciation\nLectures will be held on Tuesday
 s: 20 Oct\, 27 Oct\, 3 Nov\, 17 Nov\, at 15:00.\nAbstract: This four-lectu
 re series introduces variational inequalities to a general applied mathema
 tical audience\, pursues their finite element solution\, and applies them 
 to a geophysical problem.  Variational inequalities are partial different
 ial equation weak forms\, but subject to bounds on their solution(s).  Th
 ey reformulate how one might pose boundary conditions at a free location\;
  where the conditions apply is now determined simultaneously along with th
 e solution.  Certain variational inequalities state the KKT conditions of
  optimization problems in function spaces\, and in all cases these continu
 um models introduce admissibility and complementarity concerns into numeri
 cal solver methodology.  Examples of variational inequalities include the
  classical obstacle problem\, the problem of elastic contact\, and\, as I 
 will emphasize\, the problem of finding the extent of glaciation in a time
 - and space-varying climate.  Recent results and open problems will appea
 r\, regarding multigrid approaches\, adaptive mesh refinement\, higher-ord
 er elements\, and well-posedness of the glacier model.\n
