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. 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.
