Imperfect field
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.
