On the quadratic barycentric transport problem

Nathael Gozlan, Thibaut Le Gouic, Paul-Marie Samson

We investigate the structure of optimal transport plans, dual optimizers, and geodesic paths for the quadratic barycentric transport problem.

Common frequent hypercyclicity

Stéphane Charpentier, Romuald Ernst, Monia Mestiri +1

We provide with criteria for a family of sequences of operators to share a frequently universal vector. These criteria are variants of the classical Frequent Hypercyclicity Criteri…

Solution Operator for Non-Autonomous Perturbation of Gibbs Semigroup

Valentin Zagrebnov

The paper is devoted to a linear dynamics for non-autonomous perturbation of the Gibbs semigroup on a separable Hilbert space. It is shown that evolution family {U(t, s)} 0 $\leq$ s$\…

Trotter product formula and linear evolution equations on Hilbert spaces On the occasion of the 100th birthday of Tosio Kato

Hagen Neidhardt, Artur Stephan, Valentin Zagrebnov

The paper is devoted to evolution equations of the form $\partial$ $\partial$ t u(t) = --(A + B(t))u(t), t $\in$ I = [0, T ], on separable Hilbert spaces where A is a non-negative s…

Trotter-Kato product formulae in Dixmier ideal

Valentin Zagrebnov

It is shown that for a certain class of the Kato functions the Trotter-Kato product formulae converge in Dixmier ideal C 1, $\infty$ in topology, which is defined by the $\times$ 1,…

On restrictions of Besov functions

Julien Brasseur

In this paper, we study the smoothness of restrictions of Besov functions. It is known that for any $f \in B_p, q^{s} (R^{N})$ with $q \leq p$ we have $f(\cdot,y)\in B\_{p,q}^s…

Comments on the Chernoff $\sqrt$ n-Lemma

Valentin Zagrebnov

The Chernoff $\sqrt$ n-Lemma is revised. This concerns two aspects: an improvement of the Chernoff estimate in the strong operator topol-ogy and an operator-norm estimate for quasi…

Γ-supercyclicity

Stéphane Charpentier, Romuald Ernst, Quentin Menet

We characterize the subsets $Γ$ of $\C$ for which the notion of $Γ$ -supercyclicity coincides with the notion of hypercyclicity, where an operator $T$ on a Banach space $X$ is said…

Generic properties of Padé approximants and Padé universal series

Stéphane Charpentier, Vassili Nestoridis, Franck Wielonsky

We establish properties concerning the distribution of poles of Pad e approximants, which are generic in Baire category sense. We also investigate Pad e universal series, an analog…

A Dynamics Driven by Repeated Harmonic Perturbations

Hiroshi Tamura, Valentin Zagrebnov

We propose an exactly soluble W*-dynamical system generated by repeated harmonic perturbations of the one-mode quantum oscillator. In the present paper we deal with the case of iso…

Zigzag nanoribbons in external electric and magnetic fields

Evgeny L. Korotyaev, Anton A. Kutsenko

We consider the Schrödinger operators on zigzag nanoribbons (quasi-1D tight-binding models) in external magnetic fields and an electric potential $V$ . The magnetic field is perpend…
