• #### 1444 - Valuation Theory and Its Applications ﻿

[OWR-2014-49] (2014) - (26 Oct - 01 Nov 2014)
In recent years, the applications of valuation theory in several areas of mathematics have expanded dramatically. In this workshop, we presented applications related to algebraic geometry, number theory and model theory, ...
• #### The Varchenko Determinant of a Coxeter Arrangement ﻿

[OWP-2017-33] (Mathematisches Forschungsinstitut Oberwolfach, 2017-11-24)
The Varchenko determinant is the determinant of a matrix defined from an arrangement of hyperplanes. Varchenko proved that this determinant has a beautiful factorization. It is, however, not possible to use this factorization ...
• #### 1451 - Variational Methods for Evolution ﻿

[OWR-2014-57] (2014) - (14 Dec - 20 Dec 2014)
The workshop brought together researchers from geometry, nonlinear functional analysis, calculus of variations, partial differential equations, and stochastics around a common topic: systems whose evolution is driven by ...
• #### 1149 - Variational Methods for Evolution ﻿

[OWR-2011-55] (2011) - (04 Dec - 10 Dec 2011)
The meeting focused on the last advances in the applications of variational methods to evolution problems governed by partial differential equations. The talks covered a broad range of topics, including large deviation and ...
• #### 1746 - Variational Methods for Evolution ﻿

[OWR-2017-54] (2017) - (12 Nov - 18 Nov 2017)
Many evolutionary systems, as for example gradient flows or Hamiltonian systems, can be formulated in terms of variational principles or can be approximated using time-incremental minimization. Hence they can be studied ...
• #### 1806 - Variational Methods for the Modelling of Inelastic Solids ﻿

[OWR-2018-5] (2018) - (04 Feb - 10 Feb 2018)
This workshop brought together two communities working on the same topic from different perspectives. It strengthened the exchange of ideas between experts from both mathematics and mechanics working on a wide range of ...
• #### Varieties of Invariant Subspaces Given by Littlewood-Richardson Tableaux ﻿

[OWP-2014-01] (Mathematisches Forschungsinstitut Oberwolfach, 2014-04-25)
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 $\alpha, \beta, \gamma$, ...
• #### Vector bundles on degenerations of elliptic curves and Yang-Baxter equations ﻿

[OWP-2007-04] (Mathematisches Forschungsinstitut Oberwolfach, 2007-03-22)
In this paper we introduce the notion of a gemetric associative r-matrix attached to a genus one fibration with a section and irreducible fibres. It allows us to study degenerations of solutions of the classical Yang-Baxter ...
• #### 9945 - Verkehrsoptimierung (Traffic and Transport Optimization) ﻿

[TB-1999-44] (1999) - (07 Nov - 13 Nov 1999)
• #### Vertex-to-Self Trajectories on the Platonic Solids ﻿

[SNAP-2020-003-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2020-04-15)
We consider the problem of walking in a straight line on the surface of a Platonic solid. While the tetrahedron, octahedron, cube, and icosahedron all exhibit the same behavior, we find a remarkable difference with the ...
• #### Very general monomial valuations of P2 and a Nagata type conjecture ﻿

[OWP-2013-22] (Mathematisches Forschungsinstitut Oberwolfach, 2013-10-29)
• #### 1140 - Very High Dimensional Semiparametric Models ﻿

[OWR-2011-48] (2011) - (02 Oct - 08 Oct 2011)
Very high dimensional semiparametric models play a major role in many areas, in particular in signal detection problems when sparse signals or sparse events are hidden among high dimensional noise. Concrete examples are ...
• #### Virtual Polytopes ﻿

[OWP-2015-02] (Mathematisches Forschungsinstitut Oberwolfach, 2015-04-10)
Originating in diverse branches of mathematics, from polytope algebra and toric varieties to the theory of stressed graphs, virtual polytopes represent a natural algebraic generalization of convex polytopes. Introduced as ...
• #### Visual analysis of Spanish male mortality ﻿

[SNAP-2015-012-ENSNAP-2015-012-DE] (Mathematisches Forschungsinstitut Oberwolfach, 2015)
[also available in German] Statistical visualization uses graphical methods to gain insights from data. Here we show how a technique called principal component analysis is used to analyze mortality in Spain over about the ...
• #### 0844 - Von Neumann Algebras and Ergodic Theory of Group Actions ﻿

[OWR-2008-49] (2008) - (26 Oct - 01 Nov 2008)

• #### 0907b - Wave Motion ﻿

[OWR-2009-7] (2009) - (08 Feb - 14 Feb 2009)
This workshop was devoted to recent progress in the mathematical study of water waves, with special emphasis on nonlinear phenomena. Both aspects related to the governing equations (free boundary Euler equations) as well ...
• #### 0731 - Wavelet and Multiscale Methods ﻿

[OWR-2007-36] (2007) - (29 Jul - 04 Aug 2007)
Various scientific models demand finer and finer resolutions of relevant features. Paradoxically, increasing computational power serves to even heighten this demand. Namely, the wealth of available data itself becomes a ...
