Jan Boronski, Aleksandra Kwiatkowska
We note that homeomorphism groups of all pseudo-solenoids, including the pseudo-circle, have non-metrizable universal minimal flows.

On roundness of rotation sets
Boris Perrot, Jan Boroński, Alex Clark
Motivated by the question whether a round disk can be realized as the rotation set of a torus diffeomorphism, we study the roundness of rotation sets of a parametric family of toru…

Translation algorithms for graph covers
Jan Boroński, Henk Bruin, Przemysław Kucharski
Graph covers are a way to describe continuous maps (and homeomorphisms) of a Cantor set, more generally than e.g.\ Bratteli-Vershik systems. Every continuous map on a zero-dimensio…
