2201  Graph Theory
[OWR20221] (2022)  (02 Jan  08 Jan 2022)Graph theory is a quickly developing area of mathematics, with an increasing number of connections to various parts of mathematics and computer science. The workshop aimed at bringing together a broad range of researchers at ... 
0713  Graph Theory
[OWR200716] (2007)  (25 Mar  31 Mar 2007)This week broadly targeted both finite and infinite graph theory, as well as matroids, including their interaction with other areas of pure mathematics. The talks were complemented by informal workshops focussing on specific ... 
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 ... 
Ground State of Bose Gases Interacting through Singular Potentials
[OWP202318] (Mathematisches Forschungsinstitut Oberwolfach, 20231127)We consider a system of $N$ bosons on the threedimensional unit torus. The particles interact through repulsive pair interactions of the form $N^{3β1} v (N^βx)$ for $β\in (0,1)$. We prove the next order correction to ... 
9933  Group Actions and Curvature
[TB199933] (1999)  (15 Aug  21 Aug 1999) 
2319  Group Actions and Harmonic Analysis in Number Theory
[OWR202322] (2023)  (07 May  12 May 2023)This workshop focuses on new problems and new methods at the interface of harmonic analysis (taken in a very broad sense) and ergodic theory, with applications focused on number theory. Special emphasis is put on ... 
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 ... 
Group rings and class groups
[OWS18] (Birkhäuser Basel, 1992) 
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 ... 
2203  Groups and Dynamics: Topology, Measure, and Borel Structure
[OWR20223] (2022)  (16 Jan  22 Jan 2022)While the subjects of topological dynamics, ergodic theory, and descriptive set theory have long interacted in a variety of profitable ways, recent developments have ushered in a vigorous new phase of interplay between ...

[TB200242] (2002)  (01 Sep  07 Sep 2002) 
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. 
0817  Groups and Geometries
[OWR200820] (2008)  (20 Apr  26 Apr 2008)This was one of series of Oberwolfach workshops on Groups and Geometries which has taken place every 3 years for some time. There were three main interrelated themes: buildings and their relationship with algebraic groups; ...

[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 ...
