A refined structure theorem for polynomial return-time sets in minimal systems

Ioannis Kousek

We prove a refinement of a recent structural result in topological dynamics due to Glasscock, Koutsogiannis, Le, Moreira, Richter, and Robertson, who showed that in a minimal syste…

Sharp density conditions for infinite $B + B$ sumsets in abelian groups

Ioannis Kousek

Motivated by recent results \cite{charamaras_kousek_mountakis_radic2025BBingroups} on infinite sumsets of the form $B + B = {b_{1} + b_{2} : b_{1}, b_{2} \in B}$ in large subsets of abelian groups…

Uniqueness of a topological Furstenberg system

Ioannis Kousek, Vicente Saavedra-Araya

Given a semigroup $G$ and a bounded function $f : G \to C$ , a topological Furstenberg system of $f$ is a topological dynamical system $X = (X, (T_{g})_{g \in G})$ that…
