They were introduced by Azumaya (1951), who named them after Kurt Hensel. Azumaya originally allowed Henselian rings to be non-commutative, but most authors now restrict them to be commutative. Some standard references for Hensel rings are (Nagata 1962, Chapter VII) harv error: no target…

What does henselization do in etale cohomology theory?

WebJan 2, 2024 · The reasons henselization, or more to the point strict henselization (google it), is useful in etale cohomology is that they serve as the 'local rings' of the theory--in particular being the 'cohomologically trivial local pieces' of schemes. $\endgroup$ – … 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.
