• #### How Quantum Information Can Improve Social Welfare ﻿

[OWP-2020-13] (Mathematisches Forschungsinstitut Oberwolfach, 2020-07-16)
In [2, 18, 5, 19, 4] it has been shown that quantum resources can allow us to achieve a family of equilibria that can have sometimes a better social welfare, while guaranteeing privacy. We use graph games to propose ...
• #### How to choose a winner: the mathematics of social choice ﻿

[SNAP-2015-009-ENSNAP-2015-009-DE] (Mathematisches Forschungsinstitut Oberwolfach, 2015)
[also available in German] Suppose a group of individuals wish to choose among several options, for example electing one of several candidates to a political office or choosing the best contestant in a skating competition. ...
• #### Hölder Continuity of the Spectra for Aperiodic Hamiltonians ﻿

[OWP-2019-05] (Mathematisches Forschungsinstitut Oberwolfach, 2019-02-26)
We study the spectral location of a strongly pattern equivariant Hamiltonians arising through configurations on a colored lattice. Roughly speaking, two configurations are "close to each other" if, up to a translation, ...
• #### Hölder-Differentiability of Gibbs Distribution Functions ﻿

[OWP-2007-13] (Mathematisches Forschungsinstitut Oberwolfach, 2007-03-29)
In this paper we give non-trivial applications of the thermodynamic formalism to the theory of distribution functions of Gibbs measures (devil’s staircases) supported on limit sets of finitely generated conformal iterated ...
• #### 9919 - Hyperbolic Aspects of Fluid Dynamics ﻿

[TB-1999-20] (1999) - (09 May - 15 May 1999)
• #### 0415 - Hyperbolic Conservation Laws ﻿

[OWR-2004-18] (2004) - (04 Apr - 10 Apr 2004)
• #### 0043 - Hyperbolic Conservation Laws ﻿

[TB-2000-42] (2000) - (22 Oct - 28 Oct 2000)

[OWR-2008-56] (2008) - (07 Dec - 13 Dec 2008)
• #### 1324 - Hyperbolic Techniques for Phase Dynamics ﻿

[OWR-2013-29] (2013) - (09 Jun - 15 Jun 2013)
The progress in the theory of hyperbolic conservation laws has always been and still is driven strongly by new fields of applications. The workshop addressed aspects of modelling, analysis and numerics for fundamental ...
• #### 1625 - Hyperbolic Techniques in Modelling, Analysis and Numerics ﻿

[OWR-2016-30] (2016) - (19 Jun - 25 Jun 2016)
Several research areas are flourishing on the roots of the breakthroughs in conservation laws that took place in the last two decades. The meeting played a key role in providing contacts among the different branches that ...
• #### Ideas of Newton-Okounkov bodies ﻿

[SNAP-2015-008-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2015)
In this snapshot, we will consider the problem of finding the number of solutions to a given system of polynomial equations. This question leads to the theory of Newton polytopes and Newton-Okounkov bodies of which we will ...
• #### An Identification Therorem for PSU6(2) and its Automorphism Groups ﻿

[OWP-2011-08] (Mathematisches Forschungsinstitut Oberwolfach, 2011-05-10)
We identify the groups PSU6(2), PSU6(2):2, PSU6(2):3 and Aut(PSU6(2)) from the structure of the centralizer of an element of order 3.
• #### The Index of Singular Zeros of Harmonic Mappings of Anti-Analytic Degree One ﻿

[OWP-2017-03] (Mathematisches Forschungsinstitut Oberwolfach, 2017-02-02)
We study harmonic mappings of the form $f(z) = h(z) - \overline{z}$, where $h$ is an analytic function. In particular we are interested in the index (a generalized multiplicity) of the zeros of such functions. Outside the ...
• #### An inductive approach to coxeter arrangements and solomon's descent algebra ﻿

[OWP-2011-16] (Mathematisches Forschungsinstitut Oberwolfach, 2011-05-17)
In our recent paper [3], we claimed that both the group algebra of a finite Coxeter group W as well as the Orlik-Solomon algebra of W can be decomposed into a sum of induced one-dimensional representations of centralizers, ...
• #### Inductive Freeness of Ziegler’s Canonical Multiderivations for Reflection Arrangements ﻿

[OWP-2017-14] (Mathematisches Forschungsinstitut Oberwolfach, 2017-04-30)
Let $A$ be a free hyperplane arrangement. In 1989, Ziegler showed that the restriction $A''$ of $A$ to any hyperplane endowed with the natural multiplicity is then a free multiarrangement. We initiate a study of the stronger ...
• #### Infeasibility certificates for linear matrix inequalities ﻿

[OWP-2011-28] (Mathematisches Forschungsinstitut Oberwolfach, 2011-05-25)
Farkas' lemma is a fundamental result from linear programming providing linear certi cates for infeasibility of systems of linear inequalities. In semidefinite programming, such linear certificates only exist for strongly ...
• #### Infinite dimensional Kähler manifolds ﻿

[OWS-31] (Birkhäuser Basel, 2001)
Infinite dimensional manifolds, Lie groups and algebras arise naturally in many areas of mathematics and physics. Having been used mainly as a tool for the study of finite dimensional objects, the emphasis has changed and ...
• #### 1046a - Infinite Dimensional Lie Theory ﻿

[OWR-2010-51] (2010) - (14 Nov - 20 Nov 2010)
The workshop focussed on recent developments in infinite-dimensional Lie theory. The talks covered a broad range of topics, such as structure and classification theory of infinite-dimensional Lie algebras, geometry of ...
