1230  Calculus of Variations
[OWR201236] (2012)  (22 Jul  28 Jul 2012)Since its invention, the calculus of variations has been a central field of mathematics and physics, providing tools and techniques to study problems in geometry, physics and partial differential equations. On the one hand, ... 
1628  Calculus of Variations
[OWR201634] (2016)  (10 Jul  16 Jul 2016)The Calculus of Variations is subject with a long and distinguished history, a great deal of diverse current activity, and close connections to other fields such as geometry and mathematical physics. The July 2016 workshop ... 
Cataland: Why the Fuß?
[OWP201901] (Mathematisches Forschungsinstitut Oberwolfach, 20190121)The three main objects in noncrossing Catalan combinatorics associated to a finite Coxeter system are noncrossing partitions, clusters, and sortable elements. The first two of these have known FußCatalan generalizations. ... 
Categoric Aspects of Authentication
[OWP201205] (Mathematisches Forschungsinstitut Oberwolfach, 20120424) 
Categorical Linearly Ordered Structures
[OWP201808] (Mathematisches Forschungsinstitut Oberwolfach, 20180426)We prove that for every computable limit ordinal $\alpha$ there exists a computable linear ordering $\mathcal{A}$ which is $\Delta^0_\alpha$categorical and $\alpha$ is smallest such, but nonetheless for every isomorphic ... 
A categorical model for the virtual braid group
[OWP201119] (Mathematisches Forschungsinstitut Oberwolfach, 20110518) 
Central Limit Theorems for the Radial Spanning Tree
[OWP201418] (Mathematisches Forschungsinstitut Oberwolfach, 2014)Consider a homogeneous Poisson point process in a compact convex set in ddimensional Euclidean space which has interior points and contains the origin. The radial spanning tree is constructed by connecting each point of ... 
1815  Challenges in Optimal Control of Nonlinear PDESystems
[OWR201816] (2018)  (08 Apr  14 Apr 2018)The workshop focussed on various aspects of optimal control problems for systems of nonlinear partial diﬀerential equations. In particular, discussions around keynote presentations in the areas of optimal control of ... 
0935  Challenges in Statistical Theory: Complex Data Structures and Algorithmic Optimization
[OWR200939] (2009)  (23 Aug  29 Aug 2009)Technological developments have created a constant incoming stream of complex new data structures that need analysis. Modern statistics therefore means mathematically sophisticated new statistical theory that generates or ... 
Chaos and chaotic fluid mixing
[SNAP2015005EN] (Mathematisches Forschungsinstitut Oberwolfach, 2015)Very simple mathematical equations can give rise to surprisingly complicated, chaotic dynamics, with behavior that is sensitive to small deviations in the initial conditions. We illustrate this with a single recurrence ... 
A Characterization of Semisimple Plane Polynomial Automorphisms
[OWP200808] (Mathematisches Forschungsinstitut Oberwolfach, 20080312)It is wellknown that an element of the linear group $GL_n(\mathbb{C})$ is semisimple if and only if its conjugacy class is Zariski closed. The aim of this paper is to show that the same result holds for the group of complex ... 
A Cheeger Type Inequality in Finite Cayley Sum Graphs
[OWP201921] (Mathematisches Forschungsinstitut Oberwolfach, 20190731)  (5 May  27 July 2019)Let $G$ be a finite group and $S$ be a symmetric generating set of $G$ with $S = d$. We show that if the undirected Cayley sum graph $C_{\Sigma}(G,S)$ is an expander graph and is nonbipartite, then the spectrum of its ... 
Chirality of Real NonSingular Cubic Fourfolds and Their Pure Deformation Classification
[OWP201914] (Mathematisches Forschungsinstitut Oberwolfach, 20190515)In our previous works we have classified real nonsingular cubic hypersurfaces in the 5dimensional projective space up to equivalence that includes both real projective transformations and continuous variations of ...

1025  Classical Algebraic Geometry
[OWR201027] (2010)  (20 Jun  26 Jun 2010)Algebraic geometry studies properties of specific algebraic varieties, on the one hand, and moduli spaces of all varieties of fixed topological type on the other hand. Of special importance is the moduli space of curves, ...
