1625  Hyperbolic Techniques in Modelling, Analysis and Numerics
[OWR201630] (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 ... 
Hypergroups and Twin Buildings, I
[OWP202310] (Mathematisches Forschungsinstitut Oberwolfach, 20230619)We discuss a conjecture on thick twin buildings the verification of which is needed in order to show that thick twin buildings are mathematically equivalent to regular actions of certain twin Coxeter hypergroups. (A ... 
Ideas of NewtonOkounkov bodies
[SNAP2015008EN] (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 NewtonOkounkov bodies of which we will ... 
An Identification Therorem for PSU6(2) and its Automorphism Groups
[OWP201108] (Mathematisches Forschungsinstitut Oberwolfach, 20110510)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 AntiAnalytic Degree One
[OWP201703] (Mathematisches Forschungsinstitut Oberwolfach, 20170202)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
[OWP201116] (Mathematisches Forschungsinstitut Oberwolfach, 20110517)In our recent paper [3], we claimed that both the group algebra of a finite Coxeter group W as well as the OrlikSolomon algebra of W can be decomposed into a sum of induced onedimensional representations of centralizers, ... 
Inductive Freeness of Ziegler’s Canonical Multiderivations for Reflection Arrangements
[OWP201714] (Mathematisches Forschungsinstitut Oberwolfach, 20170430)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
[OWP201128] (Mathematisches Forschungsinstitut Oberwolfach, 20110525)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
[OWS31] (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
[OWR201051] (2010)  (14 Nov  20 Nov 2010)The workshop focussed on recent developments in infinitedimensional Lie theory. The talks covered a broad range of topics, such as structure and classification theory of infinitedimensional Lie algebras, geometry of ... 
0650  Infinite Dimensional Lie Theory
[OWR200655] (2006)  (10 Dec  16 Dec 2006)The workshop focussed on recent developments in infinitedimensional Lie theory. The talks covered a broad range of topics, such as structure and classification theory of infinitedimensional Lie algebras, geometry of ... 
0845a  Infinite Dimensional Random Dynamical Systems and Their Applications
[OWR200850] (2008)  (02 Nov  08 Nov 2008) 
Information bounds and nonparametric maximum likelihood estimation
[OWS19] (Birkhäuser Basel, 1992)This book contains the lecture notes for a DMV course presented by the authors at Gunzburg, Germany, in September, 1990. In the course we sketched the theory of information bounds for non parametric and semiparametric ... 
The ingram conjecture
[OWP201002] (Mathematisches Forschungsinstitut Oberwolfach, 2010038)We prove the Ingram Conjecture, i.e., we show that the inverse limit spaces of every two tent maps with different slopes in the interval [1,2] are nonhomeomorphic. Based on the structure obtained from the proof, we also ... 
The Initial and Terminal Cluster Sets of an Analytic Curve
[OWP201625] (Mathematisches Forschungsinstitut Oberwolfach, 20161221)For an analytic curve $\gamma : (a,b) \to \mathbb{C}$, the set of values approaches by $\gamma(t)$, as $t ↘a$ and as $t↗b$ can be any two continuua of $\mathbb{C} \cup \{\infty\}$. 
1936  Innovative Approaches to the Numerical Approximation of PDEs
[OWR201940] (2019)  (01 Sep  07 Sep 2019)This workshop was about the numerical solution of PDEs for which classical approaches, such as the finite element method, are not well suited or need further (theoretical) underpinnings. A prominent example of PDEs for ... 
Instability of point defects in a twodimensional nematic liquid crystal model
[OWP201505] (Mathematisches Forschungsinstitut Oberwolfach, 20150729)We study a class of symmetric critical points in a variational 2$D$ Landau  de Gennes model where the state of nematic liquid crystals is described by symmetric traceless $3 \times 3$ matrices. These critical points play ... 
1306a  Integral Geometry and its Applications
[OWR20135] (2013)  (03 Feb  09 Feb 2013)In recent years there has been a series of striking developments in modern integral geometry which has, in particular, lead to the discovery of new relations to several branches of pure and applied mathematics. A number ... 
The Interaction of Curvature and Topology
[SNAP2019020EN] (Mathematisches Forschungsinstitut Oberwolfach, 20191218)In this snapshot we will outline the mathematical notion of curvature by means of comparison geometry. We will then try to address questions as the ways in which curvature might influence the topology of a space, and ...
