WebHowever henselization usually behaves much better than completion, also without noetherian assumptions, as e.g. with regards to flatness, normality and reducedness. By this it is reasonable to hope that henselization of a pair may have some geometric applications, as is already happening for local henselization (e.g. [9], §18). 1.
