Witrynamiller's methods then treat the imperfect fields K on this basis. The structure theorem involves two steps: first, the construction of a discrete complete field K with a given characteristic and a given residue class field R; second, the demonstration that the so constructed field is unique.

Every imperfect field is necessarily transcendental over its prime subfield (the minimal subfield), because the latter is perfect. An example of an imperfect field is the field F q ( x), since the Frobenius sends x ↦ x p and therefore it is not surjective. poodle characteristics and traits
