Abstract
Let G be a locally compact group. We denote by 𝒮𝒰ℬ(ℝ × G) the hyperspace of closed subgroups of ℝ × G endowed with the Chabauty topology. In this paper, some general results about the connectedness of the hyperspace 𝒮𝒰ℬ(ℝ × G) are established. The main result proved here is that if G is a prosolvable group, then 𝒮𝒰ℬ(ℝ × G) is connected. We also prove a partial converse to the result just mentioned.
We thank Professor Yves de Cornulier for suggesting us this problem. It is great pleasure to thank Professor Karl Heinrich Hofmann for pointing out numerous references related to this work. We thank the anonymous referee for his/her detailed comments that helped to increase the quality of the paper.
