Testing Distributional Granger Causality With Entropic Optimal Transport
Journal of Time Series Analysis, EarlyView.ABSTRACT We develop a novel nonparametric test for Granger causality in distribution based on entropic optimal transport. Unlike classical mean‐based approaches, the proposed method directly compares the full conditional distributions of a response variable with and without the history of a candidate predictor.

On Hilbert's Inequality for Double Series and Its Applications
International Journal of Mathematics and Mathematical Sciences, 2008 This study shows that a refinement of the Hilbert inequality for double series can be established by introducing a real function u(x) and a parameter λ.

Rigidity of Hilbert metrics [PDF]
, 2017 We study the groups of isometries for Hilbert metrics on bounded open convex domains in n and show that if is such a set with a strictly convex boundary, the Hilbert geometry is asymptotically Riemannian at infinity.

Sharp Hardy’s inequalities in Hilbert spaces
Journal of Spectral TheoryWe study the behavior of the smallest possible constants d(a,b) and d_{n} in Hardy’s inequalities \int_{a}^{b}\biggl(\frac{1}{x}\int_{a}^{x}f(t)dt\biggr)^{2}\:dx\leq d(a,b){}\int_{a}^{

Measure‐valued processes for energy markets
Mathematical Finance, Volume 35, Issue 2, Page 520-566, April 2025.Abstract We introduce a framework that allows to employ (non‐negative) measure‐valued processes for energy market modeling, in particular for electricity and gas futures. Interpreting the process' spatial structure as time to maturity, we show how the Heath–Jarrow–Morton approach can be translated to this framework, thus guaranteeing arbitrage free ...

Hilbert's Type Linear Operator and Some Extensions of Hilbert's Inequality
Journal of Inequalities and Applications, 2007 The norm of a Hilbert's type linear operator is given. As applications, a new generalizations of Hilbert integral inequality, and the result of series analogues are given correspondingly.

The fundamental theorem of asset pricing with and without transaction costs
Mathematical Finance, Volume 35, Issue 2, Page 567-609, April 2025.Abstract We prove a version of the fundamental theorem of asset pricing (FTAP) in continuous time that is based on the strict no‐arbitrage condition and that is applicable to both frictionless markets and markets with proportional transaction costs. We consider a market with a single risky asset whose ask price process is higher than or equal to its ...
