1303  Graph Theory
[OWR20132] (2013)  (13 Jan  19 Jan 2013)This was a workshop on graph theory, with a comprehensive approach. Highlights included the emerging theories of sparse graph limits and of infinite matroids, new techniques for colouring graphs on surfaces, and extensions ... 
1008  Graph Theory
[OWR201011] (2010)  (21 Feb  27 Feb 2010)Highlights of this workshop on structural graph theory included new developments on graph and matroid minors, continuous structures arising as limits of finite graphs, and new approaches to higher graph connectivity via ... 
1602  Graph Theory
[OWR20162] (2016)  (10 Jan  16 Jan 2016)This workshop focused on recent developments in graph theory. These included in particular recent breakthroughs on nowherezero flows in graphs, width parameters, applications of graph sparsity in algorithms, and matroid ... 
1902  Graph Theory
[OWR20191] (2019)Graph theory is a rapidly developing area of mathematics. Recent years have seen the development of deep theories, and the increasing importance of methods from other parts of mathematics. The workshop on Graph Theory ... 
Graphical constructions for the sl(3), C2 and G2 invariants for virtual knots, virtual braids and free knots
[OWP201513] (Mathematisches Forschungsinstitut Oberwolfach, 20150731)We construct graphvalued analogues of the Kuperberg sl(3) and $G_2$ invariants for virtual knots. The restriction of the sl(3) and $G_2$ invariants for classical knots coincides with the usual Homflypt sl(3) invariant and ... 
A graphical interface for the GromovWitten theory of curves
[OWP201606] (Mathematisches Forschungsinstitut Oberwolfach, 20160510)We explore the explicit relationship between the descendant Gromov–Witten theory of target curves, operators on Fock spaces, and tropical curve counting. We prove a classical/tropical correspondence theorem for descendant ... 
Grassmannian connection between three and fourqubit observables, mermin's contextualities and black holes
[OWP201317] (Mathematisches Forschungsinstitut Oberwolfach, 20130723)We invoke some ideas from finite geometry to map bijectively 135 heptads of mutually commuting threequbit observables into 135 symmetric fourqubit ones. After labeling the elements of the former set in terms of a ...

[TB199933] (1999)  (15 Aug  21 Aug 1999) 
Group Algebras of Compact Groups. A New Way of Producing Group Hopf Algebras over Real and Complex Fields: Weakly Complete Topological Vector Spaces
[OWP201906] (Mathematisches Forschungsinstitut Oberwolfach, 20190227)Weakly complete real or complex associative algebras $A$ are necessarily projective limits of finite dimensional algebras. Their group of units $A^{1}$ is a proLie group with the associated topological Lie algebra $A_{\rm ...

1334  Group Theory, Measure, and Asymptotic Invariants
[OWR201342] (2013)  (18 Aug  24 Aug 2013)The workshop ‘Group Theory, Measure, and Asymptotic Invariants’ organized by Miklos Abert (Budapest), Damien Gaboriau (Lyon) and Andreas Thom (Leipzig) was held 18  24 August 2013. The event was a continuation of the ... 
GroupGraded Rings Satisfying the Strong Rank Condition
[OWP201922] (Mathematisches Forschungsinstitut Oberwolfach, 20190816)A ring $R$ satisfies the $\textit{strong rank condition}$ (SRC) if, for every natural number $n$, the free $R$submodules of $R^n$ all have rank $\leq n$. Let $G$ be a group and $R$ a ring strongly graded by $G$ such that ... 
0510  Groups and Geometries
[OWR200512] (2005)  (06 Mar  12 Mar 2005)The workshop Groups and Geometries was one of a series of Oberwolfach workshops which takes place every 3 years. It focused on finite simple groups, Lietype groups and their interactions with geometry.

[OWS06] (Birkhäuser Basel, 1985) 
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 ... 
1949  Groups, Dynamics, and Approximation
[OWR201955] (2019)  (01 Dec  07 Dec 2019)The workshop covered a wide range of topics, with emphasis on Geometric Group Theory, Ergodic Theory and links with Functional Analysis on the one hand and Mathematical Logic on the other. The goal of the workshop was to ...
