Hypercyclicity and Lipschitz-free operators

Christian Cobollo, Romuald Ernst, Quentin Menet +1

We study linearizations of dynamical systems and some of its topological properties. Special attention is paid to the case of Lipschitz-free operators, and they are shown to model…

On the strongly subdifferentiable points in Lipschitz-free spaces

Christian Cobollo, Sheldon Dantas, Petr Hájek +1

In this paper, we present some sufficient conditions on a metric space $M$ for which every molecule is a strongly subdifferentiable (SSD, for short) point in the Lipschitz-free spa…

Banach spaces with small weakly open subsets of the unit ball and massive sets of Daugavet and $Δ$ -points

Christian Cobollo, Daniel Isert, Ginés López-Pérez +6

We prove that there exists an equivalent norm $∥∣ \cdot ∣∥$ on $L_{\infty} [0, 1]$ with the following properties: (1) The unit ball of $(L_\infty[0,1],\Vert\vert\cdot\ver…
