Numerical problems in high spatial dimension arise in an increasing number of active and important research areas:
data mining and computational biology
ab initio electronic structure calculation
numerical solution of stochastic PDEs and
numerical solution of multiple-scale problems.
The well-known curse of dimension prevents efficient numerical treatment for most of these problems by standard discretizations of tensor product type. The resulting enormous computational challenges cannot be met merely by larger computational platforms, but require fundamentally new mathematical and algorithmic ideas.
The meeting aims at bringing together leading experts from those areas in order to compile an account of the current state of the art. We plan to address several research areas involving problems in high dimensions. Key topics are sparse grid methods, linear and nonlinear approximation theory for sparse representations, learning theory, numerical quantization, applications to mathematical finance and to stochastic PDEs, as well as models and PDEs in high dimensions (e.g. related to molecular dynamics, computational physics, climate models).
The first such workshop took place December 14-18, 2005, see http://www.igpm.rwth-aachen.de/ihp-ws
