Structuring multi-dimensional subshifts
Alexis Ballier, Emmanuel Jeandel
We study two relations on multi-dimensional subshifts: A pre-order based on the patterns configurations contain and the Cantor-Bendixson rank. We exhibit several structural propert…

Universality in symbolic dynamics constrained by Medvedev degrees
Alexis Ballier
We define a weak notion of universality in symbolic dynamics and, by generalizing a proof of Mike Hochman, we prove that this yields necessary conditions on the forbidden patterns…

Limit sets of stable Cellular Automata
Alexis Ballier
We study limit sets of stable cellular automata standing from a symbolic dynamics point of view where they are a special case of sofic shifts admitting a steady epimorphism. We pro…
