SUMMARY:Nelder Fellow lecture series – Prof Ed Bueler (University of Alas
 ka Fairbanks)
DESCRIPTION:Prof Ed Bueler (University of Alaska Fairbanks): Stokes glacier
  models with Firedrake: A tutorial\nLectures will be held on Tuesdays: 20 
 Oct\, 27 Oct\, 3 Nov\, 17 Nov\, at 15:00.\nAbstract: This four-lecture ser
 ies introduces variational inequalities to a general applied mathematical 
 audience\, pursues their finite element solution\, and applies them to a g
 eophysical problem.  Variational inequalities are partial differential eq
 uation weak forms\, but subject to bounds on their solution(s).  They ref
 ormulate how one might pose boundary conditions at a free location\; where
  the conditions apply is now determined simultaneously along with the solu
 tion.  Certain variational inequalities state the KKT conditions of optim
 ization problems in function spaces\, and in all cases these continuum mod
 els introduce admissibility and complementarity concerns into numerical so
 lver methodology.  Examples of variational inequalities include the class
 ical obstacle problem\, the problem of elastic contact\, and\, as I will e
 mphasize\, the problem of finding the extent of glaciation in a time- and 
 space-varying climate.  Recent results and open problems will appear\, re
 garding multigrid approaches\, adaptive mesh refinement\, higher-order ele
 ments\, and well-posedness of the glacier model.\n
