Irreducible $p$-local compact groups I. The structure of $p$-local compact groups of rank $1$

Abstract

Let $p$ be a fixed prime number. The main purpose of this paper is to introduce the notion of \textit{irreducible} $p$-local compact group, which provides a first reduction towards a classification of all $p$-local compact groups. In order to test this idea, in this note we describe all $p$-local compact groups of rank $1$ in terms of this notion.
