Minimality for actions of abelian semigroups on compact spaces with a free interval
Matúš Dirbák, Roman Hric, Peter Maličký +2
We study minimality for continuous actions of abelian semigroups on compact Hausdorff spaces with a free interval. First, we give a necessary and sufficient condition for such a sp…

A construction of almost automorphic minimal sets
Roman Hric, Tobias Jäger
We describe a general procedure to construct topological extensions of given skew product maps with one-dimensional fibres, by blowing up a countable number of single points to ver…

Topological entropy, homological growth and zeta functions on graphs
João F. Alves, Roman Hric, José Sousa Ramos
In connection with the Entropy Conjecture it is known that the topological entropy of a continuous graph map is bounded from below by the spectral radius of the induced map on the…
