1743b - Mini-Workshop: Reflectionless Operators: The Deift and Simon Conjectures
[OWR-2017-49] (2017) - (22 Oct - 28 Oct 2017)Reflectionless operators in one dimension are particularly amenable to inverse scattering and are intimately related to integrable systems like KdV and Toda. Recent work has indicated a strong (but not equivalent) relationship ... -
2051a - Mini-Workshop: Relativistic Fluids at the Intersection of Mathematics and Physics (online meeting)
[OWR-2020-42] (2020) - (13 Dec - 19 Dec 2020)Relativistic Hydrodynamics is the description of fluid motion in regimes where relativistic effects are important. This is the case for fluids moving at high velocities or interacting with very strong gravitational fields, ... -
1546c - Mini-Workshop: Scales in Plasticity
[OWR-2015-53] (2015) - (08 Nov - 14 Nov 2015)This mini-workshop was devoted to the current state of our understanding of dislocations (essentially slips of lines of atoms in a crystalline solid) and of their impact on the macroscopic behavior of those solids. -
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 ... -
1941c - Mini-Workshop: Self-adjoint Extensions in New Settings
[OWR-2019-47] (2019) - (06 Oct - 12 Oct 2019)The main focus of the workshop is on the analysis of boundary value problems for differential and difference operators in some non-classical geometric settings, such as fractal graphs, sub-Riemannian manifolds or non-elliptic ... -
1003c - Mini-Workshop: Semiparametric Modelling of Multivariate Economic Time Series With Changing Dynamics
[OWR-2010-5] (2010) - (17 Jan - 23 Jan 2010)Modelling multivariate time series of possibly high dimension calls for appropriate dimension-reduction, e.g. by some factor modelling, additive modelling, or some simplified parametric structure for the dynamics (i.e. the ... -
1946c - Mini-Workshop: Seshadri Constants
[OWR-2019-53] (2019) - (10 Nov - 16 Nov 2019)Seshadri constants were defined by Demailly around 30 years ago using the ampleness criterion of Seshadri. Demailly was interested in studying problems related to separation of jets of line bundles on projective varieties, ... -
0715a - Mini-Workshop: Shape Analysis for Eigenvalues
[OWR-2007-18] (2007) - (08 Apr - 14 Apr 2007)The main goal of the meeting was to bring together two mathematical communities working on the shape analysis of eigenvalues by quite different methods. On the one hand explicit solutions to optimal shape problems for ... -
1040a - Mini-Workshop: Shearlets
[OWR-2010-44] (2010) - (03 Oct - 09 Oct 2010)Over the last 20 years, multiscale methods and wavelets have revolutionized the field of applied mathematics by providing an efficient means for encoding isotropic phenomena. Directional multiscale systems, particularly ... -
1546a - Mini-Workshop: Singular Curves on K3 Surfaces and Hyperkähler Manifolds
[OWR-2015-51] (2015) - (08 Nov - 14 Nov 2015)The workshop focused on Severi varieties on $K3$ surfaces, hyperkähler manifolds and their automorphisms. The main aim was to bring researchers in deformation theory of curves and singularities together with researchers ... -
1507c - Mini-Workshop: Singularities in G2-geometry
[OWR-2015-8] (2015) - (08 Feb - 14 Feb 2015)All currently known construction methods of smooth compact $\mathrm G_2$-manifolds have been tied to certain singular $\mathrm G_2$-spaces, which in Joyce’s original construction are $\mathrm G_2$-orbifolds and in Kovalev’s ... -
1702b - Mini-Workshop: Spaces and Moduli Spaces of Riemannian Metrics
[OWR-2017-3] (2017) - (08 Jan - 14 Jan 2017)The mini-workshop focused on central questions and new results concerning spaces and moduli spaces of Riemannian metrics with lower or upper curvature bounds on open and closed manifolds and, moreover, related themes from ... -
0946a - Mini-Workshop: Spectrum of Transfer Operators: Recent Developments and Applications
[OWR-2009-49] (2009) - (08 Nov - 14 Nov 2009)Transfer operators and their spectral theory provide a unifying framework for studying stochastic properties of chaotic deterministic dynamical systems. The goal of this workshop was to widen the class of systems that can ... -
1320a - Mini-Workshop: Spherical Varieties and Automorphic Representations
[OWR-2013-24] (2013) - (12 May - 18 May 2013)This workshop brought together, for the first time, experts on spherical varieties and experts on automorphic forms, in order to discuss subjects of common interest between the two fields. Spherical varieties have a very ... -
0648a - Mini-Workshop: Statistical Methods for Inverse Problems
[OWR-2006-51] (2006) - (26 Nov - 02 Dec 2006)Inverse problems appear naturally in a broad range of applications. Numerical analysis and statistics have – often independently – developed methods for regularisation and inversion. The aim of this mini-workshop is to ... -
1307c - Mini-Workshop: Stochastic Analysis for Poisson Point Processes: Malliavin Calculus, Wiener-Ito Chaos Expansions and Stochastic Geometry
[OWR-2013-9] (2013) - (10 Feb - 16 Feb 2013)Malliavin calculus plays an important role in the stochastic analysis for Poisson point processes. This technique is tightly connected with chaotic expansions, that were introduced in the first half of the last century by ... -
