Pointwise multiple averages for sublinear functions

Sebastián Donoso, Andreas Koutsogiannis, Wenbo Sun

For any measure preserving system $(X, B, μ, T_{1}, \dots, T_{d}),$ where we assume no commutativity on the transformations $T_{i},$ $1 \leq i \leq d,$ we study the pointwise converg…

Quantitative multiple recurrence for two and three transformations

Sebastián Donoso, Wenbo Sun

We provide various counter examples for quantitative multiple recurrence problems for systems with more than one transformation. We show that $∙$ There exists an ergodic syst…

On automorphism groups of Toeplitz subshifts

Sebastián Donoso, Fabien Durand, Alejandro Maass +1

In this article we study automorphisms of Toeplitz subshifts. Such groups are abelian and any finitely generated torsion subgroup is finite and cyclic. When the complexity is non s…
