Gradient Canyons, Concentration of Curvature, and Lipschitz Invariants
[OWP201735] (Mathematisches Forschungsinstitut Oberwolfach, 20171213)We find new biLipschitz invariants of holomorphic functions of two variables by using the gradient canyons and by combining analytic and geometric viewpoints on the concentration of curvature. 
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 ... 
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 ... 
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 ...

[TB199941] (1999)  (17 Oct  23 Oct 1999) 
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 ... 
0503  Graph Theory
[OWR20053] (2005)  (16 Jan  22 Jan 2005)This is the report on an Oberwolfach conference on graph theory, held 1622 January 2005. There were three main components to the event: 5minute presentations, lectures, and workshops. All participants were asked to give ... 
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 ...

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 ...

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 ...
