The Varchenko Determinant of a Coxeter Arrangement
[OWP201733] (Mathematisches Forschungsinstitut Oberwolfach, 20171124)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 ... 
1149  Variational Methods for Evolution
[OWR201155] (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 ... 
1451  Variational Methods for Evolution
[OWR201457] (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 ... 
1746  Variational Methods for Evolution
[OWR201754] (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 timeincremental minimization. Hence they can be studied ... 
2349  Variational Methods for Evolution
[OWR202357] (2023)  (03 Dec  08 Dec 2023)Variational principles for evolutionary systems arise in many settings, both in those describing the physical world and in manmade algorithms for data science and optimization tasks. Variational principles are ... 
2038  Variational Methods for Evolution (hybrid meeting)
[OWR202029] (2020)  (13 Sep  19 Sep 2020)Variational principles for evolutionary systems take advantage of the rich toolbox provided by the theory of the calculus of variations. Such principles are available for Hamiltonian systems in classical mechanics, gradient ... 
1806  Variational Methods for the Modelling of Inelastic Solids
[OWR20185] (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 LittlewoodRichardson Tableaux
[OWP201401] (Mathematisches Forschungsinstitut Oberwolfach, 20140425)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 YangBaxter equations
[OWP200704] (Mathematisches Forschungsinstitut Oberwolfach, 20070322)In this paper we introduce the notion of a gemetric associative rmatrix attached to a genus one fibration with a section and irreducible fibres. It allows us to study degenerations of solutions of the classical YangBaxter ...

[TB199944] (1999)  (07 Nov  13 Nov 1999) 
Vertextoself trajectories on the platonic solids
[SNAP2020003EN] (Mathematisches Forschungsinstitut Oberwolfach, 20200415)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
[OWP201322] (Mathematisches Forschungsinstitut Oberwolfach, 20131029) 
1140  Very High Dimensional Semiparametric Models
[OWR201148] (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
[OWP201502] (Mathematisches Forschungsinstitut Oberwolfach, 20150410)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
[SNAP2015012EN] (Mathematisches Forschungsinstitut Oberwolfach, 2015)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 last hundred years. This ... 
Eine visuelle Analyse der Sterblichkeit männlicher Spanier
[SNAP2015012DE] (Mathematisches Forschungsinstitut Oberwolfach, 2016)Die statistische Visualisierung benutzt graphische Methoden um Erkenntnisse aus Daten zu gewinnen. Wir zeigen wie mit dem Verfahren der Hauptkomponentenanalyse die Sterblichkeit in Spanien im Laufe der letzten hundert Jahre ... 
0844  Von Neumann Algebras and Ergodic Theory of Group Actions
[OWR200849] (2008)  (26 Oct  01 Nov 2008)The theory of von Neumann algebras has seen some dramatic advances in the last few years. Von Neumann algebras are objects which can capture and analyze symmetries of mathematical or physical situations whenever these ... 
Voronoi Cells: Or How to Find the Nearest Bakery
[SNAP2024003EN] (Mathematisches Forschungsinstitut Oberwolfach, 20240905)Deciding which mall, hospital or school is closest to us is a problem we face everyday. It even comes on holidays with us, when we optimize our plans to make sure that we have enough time to visit all the attractions we ...
