BV-equivalence between triadic gravity and BF theory in three dimensions [PDF]
, 2017 The triadic description of General Relativity in three dimensions is known to be a BF theory. Diffeomorphisms, as symmetries, are easily re- covered on shell from the symmetries of BF theory. This note describes an explicit off-shell BV symplectomorphism

Dynamic Optimal Transport with Optimal Star‐Shaped Graphs
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.ABSTRACT We study an optimal transport problem in a compact convex set Ω⊂Rd$\Omega \subset \mathbb {R}^d$ where bulk transport is coupled to dynamic optimal transport on a metric graph G=(V,E,l)$ \mathsf {G}= (\mathsf {V},\mathsf {E},l)$ which is embedded in Ω$\Omega$. We prove the existence of solutions for fixed graphs.

Detecting independence of random vectors: generalized distance covariance and Gaussian covariance
Modern Stochastics: Theory and Applications, 2018 Distance covariance is a quantity to measure the dependence of two random vectors. We show that the original concept introduced and developed by Székely, Rizzo and Bakirov can be embedded into a more general framework based on symmetric Lévy measures and

Brownian Motion With Partial Resetting Conditioned to Stay Positive
Bulletin of the London Mathematical Society, Volume 58, Issue 3, March 2026.Abstract We consider Brownian motion with partial resetting, which has recently attracted a lot of attention in physics as well as the mathematics literature. We analyze the speed of convergence of this process towards stationarity as well as its quasistationary behavior.

Studienwahl mit Verstand : mit Self-Assessment online die Eignung testen [PDF]
, 2008 Die Erwartungen von Studieninteressierten weichen häufig beträchtlich von den tatsächlichen Studieninhalten und Anforderungen ab. Ein Grund dafür ist, dass viele sich nicht genügend Klarheit verschaffen, welche eigenen Stärken und Schwächen für den ...

Mixed Ehrhart polynomials [PDF]
, 2017 For lattice polytopes $P_1,\ldots, P_k \subseteq \mathbb{R}^d$, Bihan (2014) introduced the discrete mixed volume $\mathrm{DMV}(P_1,\dots,P_k)$ in analogy to the classical mixed volume.

Quasi‐Fuchsian flows and the coupled vortex equations
Bulletin of the London Mathematical Society, Volume 58, Issue 3, March 2026.Abstract We provide an alternative construction of the quasi‐Fuchsian flows introduced by Ghys. Our approach is based on the coupled vortex equations that allows to see these flows as thermostats on the unit tangent bundle of the Blaschke metric, uniquely determined by a conformal class and a holomorphic quadratic differential.

Colour-dressed hexagon tessellations for correlation functions and non-planar corrections
Journal of High Energy Physics, 2018 We continue the study of four-point correlation functions by the hexagon tessellation approach initiated in [38] and [39]. We consider planar tree-level correlation functions in N=4 $$ \mathcal{N}=4 $$ supersymmetric Yang-Mills theory involving two non ...
