"WebIn Algebra, Hilbert’s basis theorem states that a polynomial ring over a Noetherian ring is Noetherian. Algebraically, If R is a ring, let R[X] denote the ring of polynomials in the indeterminate X over R. Hilbert proved that if R is “not too large”, in the sense that if R is Noetherian, the same must be true for R[X].” ... " - Hilbert's basis theorem

WebAs Bernays noted in Hilbert and Bernays 1934, the theorem permits generalizations in two directions: first, the class of theories to which the theorem applies can be broadened to a wider class of theories. Secondly, a more general notion of consistency could be introduced, than what was indicated by Gödel in his 1931 paper.
