2201 - Graph Theory
[OWR-2022-1] (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
[OWR-2007-16] (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
[OWP-2015-13] (Mathematisches Forschungsinstitut Oberwolfach, 2015-07-31)We construct graph-valued 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 Gromov-Witten theory of curves
[OWP-2016-06] (Mathematisches Forschungsinstitut Oberwolfach, 2016-05-10)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 four-qubit observables, Mermin's contextualities and black holes
[OWP-2013-17] (Mathematisches Forschungsinstitut Oberwolfach, 2013-07-23)We invoke some ideas from finite geometry to map bijectively 135 heptads of mutually commuting three-qubit observables into 135 symmetric four-qubit ones. After labeling the elements of the former set in terms of a ... -
Ground State of Bose Gases Interacting through Singular Potentials
[OWP-2023-18] (Mathematisches Forschungsinstitut Oberwolfach, 2023-11-27)We consider a system of $N$ bosons on the three-dimensional unit torus. The particles interact through repulsive pair interactions of the form $N^{3β-1} v (N^βx)$ for $β\in (0,1)$. We prove the next order correction to ... -
9933 - Group Actions and Curvature
[TB-1999-33] (1999) - (15 Aug - 21 Aug 1999) -
2319 - Group Actions and Harmonic Analysis in Number Theory
[OWR-2023-22] (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
[OWP-2019-06] (Mathematisches Forschungsinstitut Oberwolfach, 2019-02-27)Weakly complete real or complex associative algebras $A$ are necessarily projective limits of finite dimensional algebras. Their group of units $A^{-1}$ is a pro-Lie group with the associated topological Lie algebra $A_{\rm ... -
Group rings and class groups

1334 - Group Theory, Measure, and Asymptotic Invariants
[OWR-2013-42] (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 ... -
Group-Graded Rings Satisfying the Strong Rank Condition
[OWP-2019-22] (Mathematisches Forschungsinstitut Oberwolfach, 2019-08-16)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
[OWR-2022-3] (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 ... -

0510 - Groups and Geometries
[OWR-2005-12] (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, Lie-type groups and their interactions with geometry. -

Groups with Spanier-Whitehead Duality
[OWP-2019-23] (Mathematisches Forschungsinstitut Oberwolfach, 2019-09-17)We introduce the notion of Spanier-Whitehead $K$-duality for a discrete group $G$, defined as duality in the KK-category between two $C*$-algebras which are naturally attached to the group, namely the reduced group ... -
