On Kalton's interlaced graphs and nonlinear embeddings into dual Banach spaces
Bruno de Mendonça Braga, Gilles Lancien, Colin Petitjean +1
We study the nonlinear embeddability of Banach spaces and the equi-embeddability of the family of Kalton's interlaced graphs into dual spaces. Not…

On exposed points of Lipschitz free spaces
Colin Petitjean, Antonín Procházka
In this note we prove that a molecule is an exposed point of the unit ball of a Lispchitz free space if and only if the metric segment $[x,…

On the coarse geometry of James spaces
Gilles Lancien, Colin Petitjean, Antonín Procházka
In this note we prove that the Kalton interlaced graphs do not equi-coarsely embed into the James space nor into its dual . It is a particular case of a…
