WebWhen F is the algebraic closure of a finite field, the result follows from Hilbert's Nullstellensatz. The Ax–Grothendieck theorem for complex numbers can therefore be proven by showing that a counterexample over C would translate into a counterexample in some algebraic extension of a finite field.

The inverse Galois problem over a field k, a question going back to Hilbert and Noether, asks whether every finite group occurs as a Galois group over k, i.e., as the Galois group of a Galois field extension of k.A stronger version asks for solutions to finite embedding problems over k.As in, e.g., [18, §16.4], say that a finite embedding … WebHilbert field may refer to: The Hilbert field, the minimal ordered Pythagorean field; A Hilbert field is one with minimal Kaplansky radical; Hilbert class field, the maximal abelian … high speed cameras amazon
