SUMMARY:Seminar in Numerical Analysis: Ralf Hiptmair (ETH Zürich)
DESCRIPTION:We consider scalar-valued shape functionals on sets of shapes w
 hich are small perturbations of a reference shape. The shapes are describe
 d by parameterizations and their closeness is induced by a Hilbert space s
 tructure on the parameter domain. We justify a heuristic for finding the b
 est low-dimensional parameter subspace with respect to uniformly approxima
 ting a given shape functional. We also propose an adaptive algorithm for a
 chieving a prescribed accuracy when representing the shape functional with
  a small number of shape parameters.\\r\\nFor further information about th

X-ALT-DESC:<p>We consider scalar-valued shape functionals on sets of shapes
  which are small perturbations of a reference shape. The shapes are descri
 bed by parameterizations and their closeness is induced by a Hilbert space
  structure on the parameter domain. We justify a heuristic for finding the
  best low-dimensional parameter subspace with respect to uniformly approxi
 mating a given shape functional. We also propose an adaptive algorithm for
  achieving a prescribed accuracy when representing the shape functional wi
