Regular rigid Korovin orbits
arXiv:2502.00570
Abstract
An example of an infinite regular feebly compact quasitopological group is presented such that all continuous real-valued functions on the group are constant. The example is based on the use of Korovin orbits in , where is a special regular countably compact space constructed by S.Bardyla and L.Zdomskyy and is an abstract Abelian group of an appropriate cardinality. Also, we study the interplay between the separation properties of the space and Korovin orbits in . We show in particular that if contains two nonempty disjoint open subsets, then every Korovin orbit in is Hausdorff.
