1738a  MiniWorkshop: MASAs and Automorphisms of C*Algebras
[OWR201742] (2017)  (17 Sep  23 Sep 2017)The main aim of this workshop was to study maximal abelian *subalgebras of C*algebras from various points of view. A chief motivation is the UCT problem, which asks whether all separable nuclear C*algebras satisfy the ... 
1851c  MiniWorkshop: Mathematical and Numerical Analysis of Maxwell's Equations
[OWR201857] (2018)  (16 Dec  22 Dec 2018)In this miniworkshop 17 leading mathematicians from Europe and United States met at the MFO to discuss and present new developments in the mathematical and numerical analysis of Maxwell’s equations and related systems of ... 
1416a  MiniWorkshop: Mathematical Physics meets Sparse Recovery
[OWR201418] (2014)  (13 Apr  19 Apr 2014)In recent years, there have been several fruitful interchanges of methods between the fields of sparse and lowrank recovery on the one hand and quantum information theory on the other hand. One way to understand this ...

0908b  MiniWorkshop: Product Systems and Independence in Quantum Dynamics
[OWR20099] (2009)  (15 Feb  21 Feb 2009)Quantum dynamics, both reversible (i.e., closed quantum systems) and irreversible (i.e., open quantum systems), gives rise to product systems of Hilbert spaces or, more generally, of Hilbert modules. When we consider ... 
1816c  MiniWorkshop: Superexpanders and Their Coarse Geometry
[OWR201819] (2018)  (15 Apr  21 Apr 2018)It is a deep open problem whether all expanders are superexpanders. In fact, it was already a major challenge to prove the mere existence of superexpanders. However, by now, some classes of examples are known: Lafforgue’s ...
