Orbit sets, transitivity, and sensitivity with upper semicontinuous maps
Jeison Amorocho, Javier Camargo, Sergio Macías
Given a compact metric space and an upper semicontinuous function , we explore the dynamic system . In this study, we introduce new concepts, demonstr…

More on -closed sets
Javier Camargo, Sergio Macías
We consider properties of the diagonal of a continuum that are used later in the paper. We continue the study of -closed subsets of a continuum . We prove that for a continuu…

Expansivity and unique shadowing
Chris Good, Sergio Macías, Jonathan Meddaugh +2
Let 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 is ont…
