A pointwise ergodic theorem along return times of rapidly mixing systems

SebastiÃ¡n Donoso, Alejandro Maass, Vicente Saavedra-Araya

We introduce a new class of sparse sequences that are ergodic and pointwise universally $L^{2}$ -good for ergodic averages. That is, sequences along which the ergodic averages converg…

On partial rigidity of $S$ -adic subshifts

SebastiÃ¡n Donoso, Alejandro Maass, TristÃ¡n RadiÄ

We develop combinatorial tools to study partial rigidity within the class of minimal $S$ -adic subshifts. By leveraging the combinatorial data of well-chosen Kakutani-Rokh…

On recurrence for $Z^{d}$ -Weyl systems

SebastiÃ¡n Donoso, Felipe HernÃ¡ndez, Alejandro Maass

We study the topological recurrence phenomenon of actions of locally compact abelian groups on compact metric spaces. In the case of $Z^{d}$ -actions we develop new technique…
