[OWR-2020-30] (2020) - (20 Sep - 26 Sep 2020)
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] (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] (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] (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)
• #### Dispersive Equations and Nonlinear Waves ﻿

[OWS-45] (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 ...
• #### Dominance and Transmissions in Supertropical Valuation Theory ﻿

[OWP-2011-07] (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] (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] (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 ...
• #### Drugs, herbicides, and numerical simulation ﻿

[SNAP-2014-010-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2014)
[also available in German] 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 ...
• #### 0531 - Dynamical System Methods in Fluid Dynamics ﻿

[OWR-2005-34] (2005) - (31 Jul - 06 Aug 2005)
The workshop was organized around the infusion of new techniques from dynamical systems, geometric methods, multiscale analysis, scientific computation, and control theory into traditional methods in fluid mechanics. It ...

• #### 0528 - Dynamical Systems ﻿

[OWR-2005-31] (2005) - (10 Jul - 16 Jul 2005)
This workshop, continued the biannual series at Oberwolfach on Dynamical Systems that started as the “Moser–Zehnder meeting” in 1981. The main theme of the workshop were the new results and developments in the area of ...
• #### Dynamics of Gravitational Collapse in the Axisymmetric Einstein-Vlasov System ﻿

[OWP-2020-22] (Mathematisches Forschungsinstitut Oberwolfach, 2020-12-15)
We numerically investigate the dynamcis near black hole formation of solutions to the Einstein-Vlasov system in axisymmetry. Our results are obtained using a particle-in-cell and finite difference code based on the (2+1)+1 ...
• #### 1251 - Dynamics of Patterns ﻿

[OWR-2012-60] (2012) - (16 Dec - 22 Dec 2012)
Patterns and nonlinear waves arise in many applications. Mathematical descriptions and analyses draw from a variety of fields such as partial differential equations of various types, differential and difference equations ...
• #### 0851 - Dynamics of Patterns ﻿

[OWR-2008-57] (2008) - (14 Dec - 20 Dec 2008)
This workshop focused on the dynamics of nonlinear waves and spatio-temporal patterns, which arise in functional and partial differential equations. Among the outstanding problems in this area are the dynamical selection ...
