Statement: Hemicompact \(T_2\) spaces are Lindel\"of.(A hemicompact space is a space \((X,T)\) that can be writtenas a disjoint union \(\bigcup\{K_n: n\in\omega\}\) such that(i) each \(K_n\) is a compact set in \(X\);(ii) \(K_N\subseteq K_{n+1}\) for all \(n\in\omega\); and(iii) for every compact set \(K\) in \(X\), there is an \(n\in\omega\)such that \(K\subseteq K_n\).)
