• #### Ghost Algebras of Double Burnside Algebras via Schur Functors ﻿

[OWP-2012-09] (Mathematisches Forschungsinstitut Oberwolfach, 2012-07-03)
For a finite group $G$, we introduce a multiplication on the $\mathbb{Q}$-vector space with basis $\mathscr{S}_{G\times G}$, the set of subgroups of ${G \times G}$. The resulting $\mathbb{Q}$-algebra $\tilde{A}$ can be ...
• #### Gibbs measures associated to the integrals of motion of the periodic derivative nonlinear Schrödinger equation ﻿

[OWP-2015-04] (Mathematisches Forschungsinstitut Oberwolfach, 2015-05-18)
• #### Global Variants of Hartogs' Theorem ﻿

[OWP-2018-24] (Mathematisches Forschungsinstitut Oberwolfach, 2018-11-06)
Hartogs' theorem asserts that a separately holomorphic function, defined on an open subset of $\mathbb{C}^n$, is holomorphic in all the variables. We prove a global variant of this theorem for functions defined on an open ...
• #### Gradient Canyons, Concentration of Curvature, and Lipschitz Invariants ﻿

[OWP-2017-35] (Mathematisches Forschungsinstitut Oberwolfach, 2017-12-13)
We find new bi-Lipschitz invariants of holomorphic functions of two variables by using the gradient canyons and by combining analytic and geometric viewpoints on the concentration of curvature.
• #### 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 ...
• #### 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)
