SUMMARY:Nelder Fellow lecture series – Prof Ed Bueler (University of Alas
 ka Fairbanks)
DESCRIPTION:Prof Ed Bueler (University of Alaska Fairbanks): Introduction 
 to variational inequalities and their finite element solution\nLectures wi
 ll be held on Tuesdays: 20 Oct\, 27 Oct\, 3 Nov\, 17 Nov\, at 15:00.\nAbst
 ract: This four-lecture series introduces variational inequalities to a ge
 neral applied mathematical audience\, pursues their finite element solutio
 n\, and applies them to a geophysical problem.  Variational inequalities 
 are partial differential equation weak forms\, but subject to bounds on th
 eir solution(s).  They reformulate how one might pose boundary conditions
  at a free location\; where the conditions apply is now determined simulta
 neously along with the solution.  Certain variational inequalities state 
 the KKT conditions of optimization problems in function spaces\, and in al
 l cases these continuum models introduce admissibility and complementarity
  concerns into numerical solver methodology.  Examples of variational ine
 qualities 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 ope
 n problems will appear\, regarding multigrid approaches\, adaptive mesh re
 finement\, higher-order elements\, and well-posedness of the glacier model
