Talk:Henselian ring

The definition of Henselian is incorrect as written. The article should say that P is a polynomial with coefficients in R, and that we look at the reduction of P in the ring of polynomials with coefficients in R/m. 137.82.36.10 (talk) 23:09, 28 November 2009 (UTC)

Isn't it usually called Henselian ring? Googling Hensel ring gives some 150 hits, Henselian ring some 450. Jakob.scholbach (talk) 22:00, 9 December 2007 (UTC)

Please give some references on the theory of non-commutative Henselian rings. —Preceding unsigned comment added by 128.36.235.6 (talk) 18:49, 19 December 2008 (UTC)

It was stated on the page that A is Henselian if it has one prime ideal. This is correct, but it simply means that A is a field so is not really relevant. —Preceding unsigned comment added by 131.202.24.11 (talk) 13:03, 17 June 2010 (UTC)

References for algebraic approximation
In the example that asserts that Henselization may be thought of the "algebraic part" of completion (a non-trivial result!), a reference should be given. One such reference is:

 * state theorems giving techniques for computing henselizations and strict henselizations, in particular reducing the computations to corollary 4.17 of https://www.jmilne.org/math/CourseNotes/LEC.pdf
