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 ... 
9945  Verkehrsoptimierung (Traffic and Transport Optimization)
[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
[SNAP2015012ENSNAP2015012DE] (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
[OWR200849] (2008)  (26 Oct  01 Nov 2008) 
0907b  Wave Motion
[OWR20097] (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 ...

[OWR20045] (2004)  (25 Jan  31 Jan 2004) 
Wave Phenomena
[OWS49] (Birkhäuser (Springer Nature Switzerland), 2023)This book presents the notes from the seminar on wave phenomena given in 2019 at the Mathematical Research Center in Oberwolfach. The research on wavetype problems is a fascinating and emerging field in mathematical ... 
1031  Wavelet and Multiscale Methods
[OWR201033] (2010)  (01 Aug  07 Aug 2010)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 ... 
0731  Wavelet and Multiscale Methods
[OWR200736] (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 ...

Weak Expansiveness for Actions of Sofic Groups
[OWP201405] (Mathematisches Forschungsinstitut Oberwolfach, 20140425)In this paper, we shall introduce $h$expansiveness and asymptotical $h$expansiveness for actions of sofic groups. By the definitions, each hexpansive action of sofic groups is asymptotically $h$expansive. We show that ... 
Weak*Continuity of Invariant Means on Spaces of Matrix Coefficients
[OWP202108] (Mathematisches Forschungsinstitut Oberwolfach, 20210713)With every locally compact group $G$, one can associate several interesting biinvariant subspaces $X(G)$ of the weakly almost periodic functions $\mathrm{WAP}(G)$ on $G$, each of which captures parts of the representation ... 
Weakduality based adaptive finite element methods for PDEconstrained optimization with pointwise gradient stateconstraints
[OWP201015] (Mathematisches Forschungsinstitut Oberwolfach, 2010)Adaptive finite element methods for optimization problems for second order linear elliptic partial di erential equations subject to pointwise constraints on the $\ell^2$norm of the gradient of the state are considered. ... 
Weakly Complex Homogeneous Spaces
[OWP201204] (Mathematisches Forschungsinstitut Oberwolfach, 20120424)We complete our recent classification of compact inner symmetric spaces with weakly complex tangent bundle by filling up a case which was left open, and extend this classification to the larger category of compact homogeneous ... 
Weighted Fourier inequalities for radial functions
[OWP200926] (Mathematisches Forschungsinstitut Oberwolfach, 20090319)Weighted $L^p(\mathbb{R}^n) \to L^q(\mathbb{R}^n)$ Fourier inequalities are studied. We prove PittBoas type results on integrability with power weights of the Fourier transform of a radial function.
