    • Spectral Continuity for Aperiodic Quantum Systems II. Periodic Approximations in 1D 

      [OWP-2018-27] Beckus, Siegfried; Bellissard, Jean; De Nittis, Giuseppe (Mathematisches Forschungsinstitut Oberwolfach, 2018-12-17)
      The existence and construction of periodic approximations with convergent spectra is crucial in solid state physics for the spectral study of corresponding Schrödinger operators. In a forthcoming work [9] this task was ...

    • 1502 - Spectral Theory and Weyl Functions 

      [OWR-2015-1] (2015) - (04 Jan - 10 Jan 2015)
      The focus of the workshop was on the interplay between spectral theory of differential operators, system theory, inverse problems and properties of associated classes of analytic functions, among them the classical ...

    • 0431 - Spectral Theory in Banach Spaces and Harmonic Analysis 

      [OWR-2004-36] (2004) - (25 Jul - 31 Jul 2004)
      The workshop brought together 49 researchers from 11 different countries, representing two different research areas, spectral theory in Banach spaces and harmonic analysis, in order to promote the exchange of methods and ...

    • 1944 - Subfactors and Applications 

      [OWR-2019-49] (2019) - (27 Oct - 02 Nov 2019)
      The theory of subfactors connects diverse topics in mathematics and mathematical physics such as tensor categories, vertex operator algebras, quantum groups, quantum topology, free probability, quantum field theory, ...

    • 1513 - Subfactors and Conformal Field Theory 

      [OWR-2015-16] (2015) - (22 Mar - 28 Mar 2015)
      Connections between subfactor theory and conformal field theory have been expected since the early days of the former in 1980’s, and recently we see more and more evidence for deeper relations. It was our aim to attract ...

    • 0526 - Topological and Variational Methods for Differential Equations 

      [OWR-2005-29] (2005) - (26 Jun - 02 Jul 2005)
      These notes contain the extended abstracts of the talks presented at the workshop. The range of topics includes nonlinear Schrödinger equations, singularly perturbed equations, symmetry and nodal properties of solutions, ...

    • 0710a - Transport in Multi-Dimensional Random Schrödinger Operators 

      [OWR-2007-12] (2007) - (04 Mar - 10 Mar 2007)
      Random Schrödinger operators are a topic of common interest in

    • 1911 - Uncertainty Quantification 

      [OWR-2019-12] (2019) - (10 Mar - 16 Mar 2019)
      Uncertainty quantification (UQ) is concerned with including and characterising uncertainties in mathematical models. Major steps comprise proper description of system uncertainties, analysis and efficient quantification ...

    • Unconditional Convergence of Spectral Decompositions of 1D Dirac Operators with Regular Boundary Conditions

      Given partitions $\alpha, \beta, \gamma$, the short exact sequences $0 \rightarrow N_\alpha \rightarrow N_\beta \rightarrow N_\gamma \rightarrow 0$ of nilpotent linear operators of Jordan types $\alpha, \beta, \gamma$, ...

    • Weyl-Titchmarsh Functions of Vector-Valued Sturm-Liouville Operators on the Unit Interval 

      [OWP-2008-13] Chelkak, Dmitry; Korotyaev, Evgeny (Mathematisches Forschungsinstitut Oberwolfach, 2008)
      The matrix-valued Weyl-Titchmarsh functions $M(\lambda)$ of vector-valued Sturm-Liouville operators on the unit interval with the Dirichlet boundary conditions are considered. The collection of the eigenvalues (i.e., poles ...
