WebAug 23, 2016 · So, since Henselian rings are (again, roughly) like strictly Henselian rings with topological obstruction added only at the closed point. This causes me, again perhaps incorrectly, to intuit Henselian local rings as being 'topologically trivial neighborhoods of points'. I'd be happy to hear if you think I've made some mistake in my thinking! WebIn abstract algebra, a discrete valuation ring ( DVR) is a principal ideal domain (PID) with exactly one non-zero maximal ideal . This means a DVR is an integral domain R which satisfies any one of the following equivalent conditions: R is a local principal ideal domain, and not a field. R is a valuation ring with a value group isomorphic to ...

In mathematics, a Henselian ring (or Hensel ring) is a local ring in which Hensel's lemma holds. 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 … See more In this article rings will be assumed to be commutative, though there is also a theory of non-commutative Henselian rings. • A local ring R with maximal ideal m is called Henselian if Hensel's lemma holds. This means that if … See more • Every field is a Henselian local ring. (But not every field with valuation is "Henselian" in the sense of the fourth definition above.) • See more Henselian rings are the local rings of "points" with respect to the Nisnevich topology, so the spectra of these rings do not admit non-trivial … See more For any local ring A there is a universal Henselian ring B generated by A, called the Henselization of A, introduced by Nagata (1953), such that any local homomorphism … See more
