DESCRIPTION:Speakers: Emma Seggewiss (HCM)\, Kanami Ueda\n\nThis workshop 
 is aimed at the participants in the Trimester Program "Computational multi
 fidelity\, multilevel\, and multiscale methods". It is not possible to app
 ly only for this workshop. \nGroup leaders: \n\nMoritz Hauck (Karlsruhe 
 Institute of Technology)\nJohan Wärnegård (Chalmers University)\n\nExter
 nal Speakers: \n\nAlexei Lozinski (Université Marie & Louis Pasteur)\nJo
 hannes Kraus (University of Duisburg-Essen)\nAxel Målqvist (Chalmers Univ
 ersity of Technology and University of Gothenburg)\nDaniel Peterseim (Univ
 ersity of Augsburg)\nPeter Bastian (Heidelberg University)\n\nDescription:
  \nIn many applications\, classical discretization methods are limited wh
 en dealing with heterogeneous microstructures\, especially when variations
  occur over multiple scales. Globally resolving such structures can lead t
 o an intractable number of degrees of freedom\, and not resolving them gen
 erally leads to incorrect approximations. Problem-adapted approximation sp
 aces provide an elegant solution by effectively bridging scale differences
 . The goal of this workshop is to explore optimal problem-adapted approxim
 ation spaces\, their theoretical properties\, and their efficient computat
 ion. The use of problem-adapted approximation spaces is particularly advan
 tageous in time-dependent or multi-query scenarios\, such as statistical a
 nalysis\, where multiscale constructions can be repeatedly applied to opti
 mize the simulation at coarse scales. Participants will gain insight into 
 recent advances in multiscale methods and have the opportunity to exchange
  ideas and collaborate with other workshop members and participants of the
  Junior Trimester Program.\n\nhttps://math-events.uni-bonn.de/event/281/
