• #### The Cleavage Operad and String Topology of Higher Dimension ﻿

[OWP-2011-37] (Mathematisches Forschungsinstitut Oberwolfach, 2011)
• #### Closed geodesics on surfaces and Riemannian manifolds ﻿

[SNAP-2017-005-EN] (Mathematisches Forschungsinstitut Oberwolfach, 2017-12-07)
Geodesics are special paths in surfaces and so-called Riemannian manifolds which connect close points in the shortest way. Closed geodesics are geodesics which go back to where they started. In this snapshot we talk ...
• #### 1350 - Cluster Algebras and Related Topics ﻿

[OWR-2013-58] (2013) - (08 Dec - 14 Dec 2013)
Cluster algebras are a class of commutative algebras intoduced by Fomin and Zelevinsky in 2000. Their original purpose was to obtain a combinatorial approach to Lusztig’s dual canonical bases of quantum groups and to total ...
• #### Cluster structures on simple complex lie groups and the Belavin-Drinfeld classification ﻿

[OWP-2011-10] (Mathematisches Forschungsinstitut Oberwolfach, 2011-05-12)
We study natural cluster structures in the rings of regular functions on simple complex Lie groups and Poisson-Lie structutures compatible with these cluster structures. According to our main conjecture, each class in the ...
• #### 0739 - Coagulation and Fragmentation Models ﻿

[OWR-2007-46] (2007) - (23 Sep - 29 Sep 2007)
Analysis of coagulation and fragmentation is crucial to understanding many processes of scientific and industrial importance. In recent years this has led to intensified research activities in the areas of differential ...
• #### Cocharacter-closure and spherical buildings ﻿

[OWP-2015-12] (Mathematisches Forschungsinstitut Oberwolfach, 2015-07-29)
Let $k$ be a field, let $G$ be a reductive $k$-group and $V$ an affine $k$-variety on which $G$ acts. In this note we continue our study of the notion of cocharacter-closed $G(k)$-orbits in $V$. In earlier work we used a ...
• #### Cocharacter-Closure and the Rational Hilbert-Mumford Theorem ﻿

[OWP-2014-16] (Mathematisches Forschungsinstitut Oberwolfach, 2014-12-20)
For a field $k$, let $G$ be a reductive $k$-group and $V$ an affine $k$-variety on which $G$ acts. Using the notion of cocharacter-closed $G(k)$-orbits in $V$ , we prove a rational version of the celebrated Hilbert-Mumford ...
• #### Cocycle Superrigidity and Group Actions on Stably Finite C*-Algebras ﻿

[OWP-2017-01] (Mathematisches Forschungsinstitut Oberwolfach, 2017-01-17)

[OWR-2004-32] (2004) - (04 Jul - 10 Jul 2004)
• #### 0103 - Combinatorial Convexity and Algebraic Geometry ﻿

[TB-2001-2] (2001) - (14 Jan - 20 Jan 2001)
