      A number of important recent developments in various branches of discrete geometry were presented at the workshop, which took place in hybrid format due to a pandemic situation. The presentations illustrated both the ...

    • Discrete non-commutative integrability: the proof of a conjecture by M. Kontsevich 

      [OWP-2009-24] Di Francesco, Philippe; Kedem, Rinat (Mathematisches Forschungsinstitut Oberwolfach, 2009-03-17)
      We prove a conjecture of Kontsevich regarding the solutions of rank two recursion relations for non-commutative variables which, in the commutative case, reduce to rank two cluster algebras of affine type. The conjecture ...

    • Discrete Translates in Lp (R) 

      [OWP-2015-09] Olevskij, Aleksandr M.; Ulanovskii, Alexander (Mathematisches Forschungsinstitut Oberwolfach, 2015-06-18)
      A set $\Lambda$ is called $p$-spectral if there is a function $g \in L^p (\mathbb{R})$ such that all $\Lambda$-translates $\{g(t-\lambda),\lambda \in \Lambda\}$ span $L^p(\mathbb{R})$. We prove that exponentially small ...

    • Discretization of Inherent ODEs and the Geometric Integration of DAEs with Symmetries 

      [OWP-2022-10] Kunkel, Peter; Mehrmann, Volker (Mathematisches Forschungsinstitut Oberwolfach, 2022-06-08)
      Discretization methods for differential-algebraic equations (DAEs) are considered that are based on the integration of an associated inherent ordinary differential equation (ODE). This allows to make use of any discretization ...

    • 0813 - Disordered Systems: Random Schrödinger Operators and Random Matrices 

      [OWR-2008-16] (2008) - (23 Mar - 29 Mar 2008)
      The spectral analysis of random operators plays a central role for the understanding of quantum systems with disorder. Two distinct types of ensembles are of particular significance: Random Schrödinger operators and random ...

    • Dispersive Equations and Nonlinear Waves 

      [OWS-45] Koch, Herbert; Tataru, Daniel; Vişan, Monica (Birkhäuser Basel, 2014)
      The first part of the book provides an introduction to key tools and techniques in dispersive equations: Strichartz estimates, bilinear estimates, modulation and adapted function spaces, with an application to the generalized ...

    • Domain-Scaled Regular Variation: Mathematical Foundations for a New Tail Process 

      [OWP-2025-02] Strokorb, Kirstin; Oesting, Marco; De Fondeville, Raphaël (Mathematisches Forschungsinstitut Oberwolfach, 2025-02)
      Threshold exceedances of stochastic processes in space and time often appear to be more localized the more extreme they are. While classical regularly varying stochastic processes cannot model this effect, we introduce an ...

    • Dominance and Transmissions in Supertropical Valuation Theory 

      [OWP-2011-07] Izhakian, Zur; Knebusch, Manfred; Rowen, Louis (Mathematisches Forschungsinstitut Oberwolfach, 2011)
      This paper is a sequel of [IKR1], where we defined supervaluations on a commutative ring $R$ and studied a dominance relation $\Phi >= v$ between supervaluations $\varphi$ and $\upsilon$ on $R$, aiming at an enrichment of ...

    • Domino tilings of the Aztec diamond 

      [SNAP-2015-016-EN] Rué, Juanjo (Mathematisches Forschungsinstitut Oberwolfach, 2015)
      Imagine you have a cutout from a piece of squared paper and a pile of dominoes, each of which can cover exactly two squares of the squared paper. How many different ways are there to cover the entire paper cutout with ...

    • Drawing large pictures at random : Oberwolfach Lecture 2007 

      [OWP-2007-08] Wendelin, Werner (Mathematisches Forschungsinstitut Oberwolfach, 2007)
      This lecture is of very introductory nature. The goal will be to describe specific concrete questions, and to use them as a tool to convey some general ideas. Let me therefore skip the general introduction and immediately ...

    • Drogen, Herbizide und numerische Simulation 

      [SNAP-2014-010-DE] Benner, Peter; Mena, Hermann; Schneider, René (Mathematisches Forschungsinstitut Oberwolfach, 2017-08)
      Die kolumbianische Regierung versprüht Unkrautbekämpfungsmittel (Herbizide) über Coca-Feldern, um die Drogenproduktion im Land zu reduzieren. Sprühverwehungen entlang der Grenze Kolumbiens zu Ecuador wurden zu einem ...

    • Drugs, herbicides, and numerical simulation 

      [SNAP-2014-010-EN] Benner, Peter; Mena, Hermann; Schneider, René (Mathematisches Forschungsinstitut Oberwolfach, 2014)
      The Colombian government sprays coca fields with herbicides in an effort to reduce drug production. Spray drifts at the Ecuador-Colombia border became an international issue. We developed a mathematical model for the ...
