Concrete self-similar representations of some subgroups of the Baer–Specker group
Abstract
In this work we study the self-similarity of infinite products of the group of the integers. In [A. C. Dantas, T. M. G. Santos and S. N. Sidki, Self-similar abelian groups and their centralizers, Groups Geom. Dyn. 17 (2023) 1–23], the authors ask if there is a self-similar free abelian group of uncountable rank. On the other hand, in [L. Bartholdi and S. N. Sidki, Self-similar products of groups, Groups Geom. Dyn. 14(1) (2020) 107–115] is asked if the Baer–Specker group [Formula: see text] is self-similar (by a result of R. Baer, this group is not free abelian). We answer both questions positively.
