A set of 2-recurrence whose perfect squares do not form a set of measurable recurrence

John T. Griesmer

We say that $S \subset Z$ is a set of $k$ -recurrence if for every measure preserving transformation $T$ of a probability measure space $(X, μ)$ and every $A \subseteq X$ with $…

Bohr sets in sumsets II: countable abelian groups

John T. Griesmer, Anh N. Le, Thái Hoàng Lê

We prove three results concerning the existence of Bohr sets in threefold sumsets. More precisely, letting $G$ be a countable discrete abelian group and $ϕ_{1}, ϕ_{2}, ϕ_{3} : G \to G$ be…
