1240a - Mini-Workshop: Nichols Algebras and Weyl Groupoids
[OWR-2012-47] (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 mini-workshop, introductions ... -
0910c - Mini-Workshop: Non-Negativity is a Quantum Phenomenon
[OWR-2009-14] (2009) - (01 Mar - 07 Mar 2009)In recent publications, the same combinatorial description has arisen for three separate objects of interest: non-negative cells in the real grassmannian (Postnikov, Williams); torus orbits of symplectic leaves in the ... -
2106a - Mini-Workshop: Non-semisimple Tensor Categories and Their Semisimplification (online meeting)
[OWR-2021-7] (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 - Mini-Workshop: Product Systems and Independence in Quantum Dynamics
[OWR-2009-9] (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 - Mini-Workshop: Rank One Groups and Exceptional Algebraic Groups
[OWR-2019-52] (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 - Mini-Workshop: Support Varieties
[OWR-2009-10] (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 - Mini-Workshop: Three Facets of R-Matrices (hybrid meeting)
[OWR-2021-51] (2021) - (17 Oct - 23 Oct 2021)By definition, an $R$-matrix with spectral parameter is a solution to the Yang-Baxter 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 ... -
