Shearer's inequality and Infimum Rule for Shannon entropy and topological entropy

open access: yes, 2015
We review subbadditivity properties of Shannon entropy, in particular, from the Shearer's inequality we derive the "infimum rule" for actions of amenable groups. We briefly discuss applicability of the "infimum formula" to actions of other groups.

The role of continuity and expansiveness on leo and periodic specification properties

open access: yes, 2020
In this short note we prove that a continuous map which is locally eventually onto and is expansive satisfies the periodic specification property. We also discuss the role of continuity as a key condition in the previous characterization.

Positive Entropy Through Pointwise Dynamics

open access: yes, 2019
We define some pointwise properties of topological dynamical systems and give pointwise conditions for such a system possesses positive topological entropy.
