INVARIANTS OF ALGEBRAIC VARIETIES OVER IMPERFECT FIELDS …

WitrynaIn fact, most fields that appear in practice are perfect. The imperfect case arises mainly in algebraic geometry. Perfect closure and perfection The first condition says that, in characteristic p, a field adjoined with all p - th roots ( usually denoted by ) is perfect; it is called the perfect closure, denoted by kp. 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).
