[OWR-2019-35] (2019) - (28 Jul - 03 Aug 2019)
Many physical processes in material sciences or geophysics are characterized by inherently complex interactions across a large range of non-separable scales in space and time. The resolution of all features on all scales ...
• #### 1426 - Computational Multiscale Methods ﻿

[OWR-2014-30] (2014) - (22 Jun - 28 Jun 2014)
Almost all processes in engineering and the sciences are characterised by the complicated relation of features on a large range of nonseparable spatial and time scales. The workshop concerned the computer-aided simulation ...
• #### Computational Optimal Transport ﻿

[SNAP-2017-008-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2017-12-21)
Optimal transport is the mathematical discipline of matching supply to demand while minimizing shipping costs. This matching problem becomes extremely challenging as the quantity of supply and demand points increases; ...

• #### Computing the long term evolution of the solar system with geometric numerical integrators ﻿

[SNAP-2017-009-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2017-12-27)
Simulating the dynamics of the Sun–Earth–Moon system with a standard algorithm yields a dramatically wrong solution, predicting that the Moon is ejected from its orbit. In contrast, a well chosen algorithm with the ...
• #### Computing with symmetries ﻿

[SNAP-2018-003-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2018-03-06)
Group theory is the study of symmetry, and has many applications both within and outside mathematics. In this snapshot, we give a brief introduction to symmetries, and how to compute with them.
• #### Configuration spaces and braid groups ﻿

[SNAP-2019-011-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2019-10-08)
