Free shipping for many products! Most fields that are encountered in practice are perfect. The imperfect case arises mainly in algebraic geometry in characteristic p > 0. Every imperfect field is necessarily transcendental over its prime subfield (the minimal subfield), because the latter is perfect. Zobacz więcej In algebra, a field k is perfect if any one of the following equivalent conditions holds: • Every irreducible polynomial over k has distinct roots. • Every irreducible polynomial over k is separable. Zobacz więcej One of the equivalent conditions says that, in characteristic p, a field adjoined with all p -th roots (r ≥ 1) is perfect; it is called the perfect closure of k and usually denoted by Zobacz więcej • "Perfect field", Encyclopedia of Mathematics, EMS Press, 2001 [1994] Zobacz więcej Examples of perfect fields are: • every field of characteristic zero, so $${\displaystyle \mathbb {Q} }$$ and every finite … Zobacz więcej Any finitely generated field extension K over a perfect field k is separably generated, i.e. admits a separating transcendence base, that is, a transcendence base Γ such that K is separably algebraic over k(Γ).

Abundance theorem for surfaces over imperfect fields

WitrynaIn algebra, a purely inseparable extension of fields is an extension k ⊆ K of fields of characteristic p > 0 such that every element of K is a root of an equation of the form x q = a, with q a power of p and a in k.Purely inseparable extensions are sometimes called radicial extensions, which should not be confused with the similar-sounding but more … Witryna4 lut 2015 · Title: Abundance theorem for surfaces over imperfect fields.

WitrynaFor a field F to possess a non-trivial purely inseparable extension, it must necessarily be an infinite field of prime characteristic (i.e. specifically, imperfect), since any algebraic extension of a perfect field is necessarily separable.[6] The study of separable extensions in their own right has far-reaching consequences.
