Countably compact groups having minimal infinite powers
Dikran Dikranjan, Vladimir Uspenskij
We answer the question, raised more than thirty years ago, on whether the power (G raised to the power omega) of a countably compact minimal Abelian group G is minimal, by showing…
Groups with cofinite Zariski topology and potential density
Marco Bonatto, Dikran Dikranjan, Daniele Toller
Tkachenko and Yaschenko [34] characterized the abelian groups G such that all proper unconditionally closed subsets of G are finite, these are precisely the abelian groups G having…
Metric vs topological receptive entropy of semigroup actions
Andrzej Biś, Dikran Dikranjan, Anna Giordano Bruno +1
We study the receptive metric entropy for semigroup actions on probability spaces, inspired by a similar notion of topological entropy introduced by Hofmann and Stoyanov. We analyz…
