Entropy and complexity in a strong orbit equivalence class via pseudo-Toeplitz subshifts
Paulina Cecchi-Bernales, Sebastián Donoso
We develop a method for constructing minimal subshifts with a prescribed bound on the factor complexity within any strong orbit equivalence (SOE) class. This implies realizations o…
Non-determinism in group actions and topological minimal self-joinings
Nicolás Bitar, Sebastián Donoso, Samuel Petite
We study the topological and geometrical aspects of non-determinism in group actions, generalizing the notion of non-expansive direction for abelian actions. Under suitable conditi…
Partition regularity in imaginary quadratic rings of integers
Sebastián Donoso, Andreu Ferré Moragues, Andreas Koutsogiannis +1
We obtain partition regularity results for homogeneous quadratic equations whose parametrized solutions admit nice factorizations into linear forms over rings of integers of imagin…
Ergodic averages for commutative transformations along return times
Sebastián Donoso, Sovanlal Mondal, Vicente Saavedra-Araya
In this paper, we extend recent results on the convergence of ergodic averages along sequences generated by return times to shrinking targets in rapidly mixing systems, partially a…
Pointwise ergodic averages along the Omega function in number fields
Diego Céspedes, Sebastián Donoso
We study a general criterion for guaranteeing that an ergodic average exhibits the strong sweeping-out property. This result implies, in particular, the failure of pointwise conver…
Resolving the joint ergodicity problem for Hardy sequences
Sebastián Donoso, Andreas Koutsogiannis, Borys Kuca +2
The joint ergodicity classification problem aims to characterize those sequences which are jointly ergodic along an arbitrary dynamical system if and only if they satisfy two natur…
