Title: Countable extensions of compact lines
Abstract: For a compact space \(K\), we say that \(L\) is a countable discrete extension of \(K\) if \(L\) is compact and consists of \(K\) and a countable set of isolated points. We investigate some properties of such extenions for separable compact lines \(K\). This is directly related to properties of almost chains of subsets of \( \mathbb{N}\).
