Unveiling universality, encloseness, and orthogonality in dynamics

J. Aaronson, A. I. Danilenko, J. Kułaga-Przymus +1

Motivated by Sarnak's conjecture on Möbius orthogonality, we investigate the general problem of orthogonality for a bounded sequence to topological models of characteristic classes…

On arithmetic functions orthogonal to deterministic sequences

Adam Kanigowski, Joanna Kulaga-Przymus, Mariusz Lemańczyk +1

We prove Veech's conjecture on the equivalence of Sarnak's conjecture on Möbius orthogonality with a Kolmogorov type property of Furstenberg systems of the M\''obius function. This…

Entropy rate of product of independent processes

Joanna Kułaga-Przymus, Michał Lemańczyk

We study the multiplicative version of the classical Furstenberg's filtering problem, where instead of the sum one considers the product $\mathbf{X}\cdot \m…

Hereditary subshifts whose measure of maximal entropy has no Gibbs property

Joanna Kułaga-Przymus, Michał Lemańczyk

We show that the measure of maximal entropy for the hereditary closure of a -free subshift has the Gibbs property if and only if the Mirsky measure of the subshift is…

Sarnak's Conjecture -- what's new

S. Ferenczi, J. Kułaga-Przymus, M. Lemańczyk

An overview of last seven years results concerning Sarnak's conjecture on Möbius disjointness is presented, focusing on ergodic theory aspects of the conjecture.

A structure theorem for level sets of multiplicative functions and applications

Vitaly Bergelson, Joanna Kułaga-Przymus, Mariusz Lemańczyk +1

Given a level set of an arbitrary multiplicative function , we establish, by building on the fundamental work of Frantzikinakis and Host [13,14], a structure theorem which g…

Rationally almost periodic sequences, polynomial multiple recurrence and symbolic dynamics

Vitaly Bergelson, Joanna Kułaga-Przymus, Mariusz Lemańczyk +1

A set is called rational if it is well-approximable by finite unions of arithmetic progressions. Examples of rational sets include many classical sets of numb…

Multiple mixing and parabolic divergence in smooth area-preserving flows on higher genus surfaces

Adam Kanigowski, Joanna Kułaga-Przymus, Corinna Ulcigrai

We consider typical area preserving flows on higher genus surfaces and prove that the flow restricted to mixing minimal components is mixing of all orders, thus answering affimativ…

Substitutions and Möbius disjointness

S. Ferenczi, J. Kułaga-Przymus, M. Lemańczyk +1

We show that Sarnak's conjecture on Möbius disjointness holds for all subshifts given by bijective substitutions and some other similar dynamical systems, e.g.\ those generated by…

Hereditary subshifts whose simplex of invariant measures is Poulsen

Joanna Kułaga-Przymus, Mariusz Lemańczyk, Benjamin Weiss

We give a sufficient condition for the simplex of invariant measures for a hereditary system to be Poulsen. In particular, we show that this simplex is Poulsen in case of positive…

-free integers in number fields and dynamics

Francisco Araújo, Aurelia Dymek, Joanna Kułaga-Przymus

In 2010, Sarnak initiated the study of the dynamics of the system determined by the square of the Möbius function (the characteristic function of the square-free integers). We deal…

The Chowla and the Sarnak conjectures from ergodic theory point of view

El Houcein El Abdalaoui, Joanna Kulaga-Przymus, Mariusz Lemanczyk +1

We rephrase the conditions from the Chowla and the Sarnak conjectures in abstract setting, that is, for sequences of numbers in {-1,0,1}, and introduce several natural generalizati…
