[OWR201118] (2011)  (03 Apr  08 Apr 2011)This Arbeitsgemeinschaft focused on the interplay among rational homotopy theory, differential geometry and the physics of string topology. The talks centered on one hand on how geometry and string topology make use of ... 
1041  Arbeitsgemeinschaft: Topological Robotics
[OWR201047] (2010)  (10 Oct  16 Oct 2010)The purpose of the Arbeitsgemeinschaft was to enable PhD students and researchers to study Topological Robotics, a new field investigating topological problems motivated by robotics and engineering as well as problems of ... 
1030  Cohomology of Finite Groups: Interactions and Applications
[OWR201032] (2010)  (25 Jul  31 Jul 2010)The cohomology of finite groups is an important tool in many subjects including representation theory and algebraic topology. This meeting was the third in a series that has emphasized the interactions of group cohomology ...

[OWR200829] (2008)  (29 Jun  05 Jul 2008) 
1542  Computational Geometric and Algebraic Topology
[OWR201545] (2015)  (11 Oct  17 Oct 2015)Computational topology is a young, emerging field of mathematics that seeks out practical algorithmic methods for solving complex and fundamental problems in geometry and topology. It draws on a wide variety of techniques ... 
Definable orthogonality classes in accessible categories are small
[OWP201114] (Mathematisches Forschungsinstitut Oberwolfach, 20110515)We lower substantially the strength of the assumptions needed for the validity of certain results in category theory and homotopy theory which were known to follow from Vopenka's principle. We prove that the necessary ... 
1619  Factorization Algebras and Functorial Field Theories
[OWR201625] (2016)  (08 May  14 May 2016)Factorization algebras are a new mathematical approach to quantum field theory. They are related to functorial field theories, another approach to quantum field theory. Factorization algebras also figure in current research ...

1504  Geometric Topology
[OWR20153] (2015)  (18 Jan  24 Jan 2015)Geometric topology has seen significant advances in the understanding and application of infinite symmetries and of the principles behind them. On the one hand, for advances in (geometric) group theory, tools from algebraic ... 
0524  Geometric Topology and Connections with Quantum Field Theory
[OWR200527] (2005)  (12 Jun  18 Jun 2005)In recent years, the interplay between traditional geometric topology and theoretical physics, in particular quantum field theory, has played a significant role in the work of many researchers. The idea of this workshop ... 
Groups with SpanierWhitehead Duality
[OWP201923] (Mathematisches Forschungsinstitut Oberwolfach, 20190917)We introduce the notion of SpanierWhitehead $K$duality for a discrete group $G$, defined as duality in the KKcategory between two $C*$algebras which are naturally attached to the group, namely the reduced group ... 
Hight functions on quaternionic Stiefel manifolds
[OWP201510] (Mathematisches Forschungsinstitut Oberwolfach, 20150729)In this note, we study height functions on quaternionic Stiefel manifolds and prove that all these height functions are MorseBott. Among them, we characterize the Morse functions and give a lower bound for their number ...
