Borel factors and embeddings of systems in subshifts

Nishant Chandgotia, Spencer Unger

In this paper we study the combinatorics of free Borel actions of the group $Z^{d}$ on Polish spaces. Building upon recent work by Chandgotia and Meyerovitch, we introduce pr…

Predictive Sets

Nishant Chandgotia, Benjamin Weiss

A set $P \subset N$ is called predictive if for any zero entropy finite-valued stationary process $(X_{i})_{i \in Z}$ , $X_{0}$ is measurable with respect to $(X_i)_{i\in…

Mixing properties of colorings of the $Z^{d}$ lattice

Noga Alon, Raimundo Briceño, Nishant Chandgotia +2

We study and classify proper $q$ -colorings of the $Z^{d}$ lattice, identifying three regimes where different combinatorial behavior holds: (1) When $q \leq d + 1$ , there exist fr…

Borel subsystems and ergodic universality for compact $Z^{d}$ -systems via specification and beyond

Nishant Chandgotia, Tom Meyerovitch

A Borel system $(X, S)$ is `almost Borel universal' if any free Borel dynamical system $(Y, T)$ of strictly lower entropy is isomorphic to a Borel subsystem of $(X, S)$ , after removin…
