1320c  MiniWorkshop: Localising and Tilting in Abelian and Triangulated Categories
[OWR201326] (2013)  (12 May  18 May 2013)The workshop brought together experts on localisation theory and tilting theory from different parts of mathematics with the aim of fully exploiting the power of some recent developments in so far rather independent contexts. ... 
1240a  MiniWorkshop: Nichols Algebras and Weyl Groupoids
[OWR201247] (2012)  (30 Sep  06 Oct 2012)Nichols algebras are graded braided Hopf algebras satisfying a universal property. Many structural results of a Nichols algebra can be obtained by studying itsWeyl groupoid and its homology. In the miniworkshop, introductions ... 
0910c  MiniWorkshop: NonNegativity is a Quantum Phenomenon
[OWR200914] (2009)  (01 Mar  07 Mar 2009)In recent publications, the same combinatorial description has arisen for three separate objects of interest: nonnegative cells in the real grassmannian (Postnikov, Williams); torus orbits of symplectic leaves in the ... 
2106a  MiniWorkshop: Nonsemisimple Tensor Categories and Their Semisimplification (online meeting)
[OWR20217] (2021)  (07 Feb  13 Feb 2021)Finite tensor categories are, despite their many applications and great interest, notoriously hard to classify. Among them, the semisimple ones (called fusion categories) have been intensively studied. Those with ... 
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 ... 
1946b  MiniWorkshop: Rank One Groups and Exceptional Algebraic Groups
[OWR201952] (2019)  (10 Nov  16 Nov 2019)Rank one groups are a class of doubly transitive groups that are natural generalizations of the groups $ \operatorname{SL}_2(k) $. The most interesting examples arise from exceptional algebraic groups of relative rank ... 
0908c  MiniWorkshop: Support Varieties
[OWR200910] (2009)  (15 Feb  21 Feb 2009)The notion of support is a fundamental concept which provides a geometric approach for studying various algebraic structures. The prototype for this has been Quillen’s description of the algebraic variety corresponding to ... 
2142a  MiniWorkshop: Three Facets of RMatrices (hybrid meeting)
[OWR202151] (2021)  (17 Oct  23 Oct 2021)By definition, an $R$matrix with spectral parameter is a solution to the YangBaxter equation, introduced in the 1970's by C.N. Yang and R.J. Baxter. Such a matrix encodes the Boltzmann weights of a lattice model of ... 
0618b  MiniWorkshop: Zeta Functions, Index and Twisted KTheory; Interactions with Physics
[OWR200621] (2006)  (30 Apr  06 May 2006)The meeting provided an opportunity for number theorists, physicists, topologists and analysts to discuss recent developments and interactions in the area of multiple zeta functions, twisted Ktheory, Hopf algebras, and ... 
1331  Multiscale and HighDimensional Problems
[OWR201339] (2013)  (28 Jul  03 Aug 2013)Highdimensional problems appear naturally in various scientific areas, such as PDEs describing complex processes in computational chemistry and physics, or stochastic or parameterdependent PDEs leading to deterministic ... 
1337  Noncommutative Geometry
[OWR201345] (2013)  (08 Sep  14 Sep 2013)Noncommutative Geometry applies ideas from geometry to mathematical structures determined by noncommuting variables. This meeting emphasized the connections of Noncommutative Geometry to number theory and ergodic theory.
