Conditions for \(L_0(T)\) to be a Polish space

The author proves that \(L_0(T)\) is Polish if \(T\) is compact and \(\Sigma\) countably generated. Here \((T,d)\) denotes a metric space, \((\Omega,\Sigma,p)\) a \(\sigma\)-finite measure space and \(L_0(T)\) the set of measurable functions \(\Omega\to T\) with topology \(N(x,\varepsilon)=\{y\in L_0(T)\mid p(d(x,y)>\varepsilon)
