2119a - Mini-Workshop: Analysis of Data-driven Optimal Control (hybrid meeting)
[OWR-2021-23] (2021) - (09 May - 15 May 2021)This hybrid mini-workshop discussed recent mathematical methods for analyzing the opportunities and limitations of data-driven and machine-learning approaches to optimal feedback control. The analysis concerned all aspects ... -
2119b - Mini-Workshop: Mathematics of Dissipation – Dynamics, Data and Control (hybrid meeting)
[OWR-2021-24] (2021) - (09 May - 15 May 2021)Dissipation of energy --- as well as its sibling the increase of entropy --- are fundamental facts inherent to any physical system. The concept of dissipativity has been extended to a more general system theoretic setting ... -
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 ... -
2106c - Mini-Workshop: Nonpositively Curved Complexes (online meeting)
[OWR-2021-8] (2021) - (07 Feb - 13 Feb 2021)The leading theme of the meeting was to understand nonpositively curved complexes and groups acting on them. Motivations, questions, results, and techniques being presented and discussed come from various areas of ... -
2149b - Mini-Workshop: Scattering Amplitudes, Cluster Algebras, and Positive Geometries (hybrid meeting)
[OWR-2021-57] (2021) - (05 Dec - 11 Dec 2021)Cluster algebras were developed by Fomin and Zelevinsky about twenty years ago. While the initial motivation came from within algebra (total positivity, canonical bases), it quickly became clear that cluster algebras ... -
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 ... -
2149c - Mini-Workshop: Variable Curvature Bounds, Analysis and Topology on Dirichlet Spaces (hybrid meeting)
[OWR-2021-58] (2021) - (05 Dec - 11 Dec 2021)A Dirichlet form $\mathcal{E}$ is a densely defined bilinear form on a Hilbert space of the form $L^2(X,\mu)$, subject to some additional properties, which make sure that $\mathcal{E}$ can be considered as a natural ... -
2105 - Moduli spaces and Modular forms (hybrid meeting)
[OWR-2021-6] (2021) - (31 Jan - 06 Feb 2021)The relation between moduli spaces and modular forms goes back to the theory of elliptic curves. On the one hand both topics experience their own growth and development, but from time to time new unexpected links show ... -
2102 - Nonstandard Finite Element Methods (hybrid meeting)
[OWR-2021-3] (2021) - (10 Jan - 16 Jan 2021)Finite element methodologies dominate the computational approaches for the solution to partial differential equations and nonstandard finite element schemes most urgently require mathematical insight in their design. The ... -
2126b - Numerical Methods for Fully Nonlinear and Related PDEs (hybrid meeting)
[OWR-2021-31] (2021) - (27 Jun - 03 Jul 2021)The aim of this workshop was to discuss the challenges, latest trends and advancements on numerical methods for fully nonlinear PDEs. The construction of numerical schemes and their convergence analysis is still an emerging ... -
2139 - Singularities (hybrid meeting)
[OWR-2021-47] (2021) - (26 Sep - 02 Oct 2021)Singularity theory concerns local and global structure of singularities of (algebraic) varieties and maps. As such, it combines tools from algebraic geometry, complex analysis, topology, algebra and combinatorics. -
