Let X, Tx and m be given.
Assume Hloc: locally_m_euclidean X Tx m.
Assume Hnorm: normal_space X Tx.
We will prove Hausdorff_space X Tx.
We prove the intermediate claim HT1: T1_space X Tx.
An exact proof term for the current goal is (locally_m_euclidean_implies_T1 X Tx m Hloc).
An exact proof term for the current goal is (normal_T1_implies_Hausdorff X Tx Hnorm HT1).
