Shifts of finite type as fundamental objects in the theory of shadowing

C Good, J Meddaugh - Inventiones mathematicae, 2020 - Springer
Shifts of finite type and the notion of shadowing, or pseudo-orbit tracing, are powerful tools in
the study of dynamical systems. In this paper we prove that there is a deep and fundamental …

Expansivity and unique shadowing

C Good, S Macías, J Meddaugh, J Mitchell… - Proceedings of the …, 2021 - ams.org
Let $ f\colon X\to X $ be a continuous function on a compact metric space. We show that
shadowing is equivalent to backwards shadowing and two-sided shadowing when the map …

Ultrafilters and Ramsey-type shadowing phenomena in topological dynamics

W Brian, P Oprocha - Israel Journal of Mathematics, 2018 - Springer
We explore five variants of the Ramsey shadowing property. Each variant is a different way
of formalizing the notion that, in a given dynamical system, every sequence of points looks …

[PDF][PDF] Diametric Colourings in Ultrametric Spaces

JR GAMEROFF - math.mcgill.ca
Let ΓX denote the family of compact subsets of (X, d). A colouring χ: ΓX→[k] is diametric if
every pair of compact subsets with equal diameters receive the same colour. A free ultrafilter …
