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].” ... Web1 Hilbert's basis theorem (1888) is usually stated as: "If R is a Noetherian ring, then R [X] is a Noetherian ring." This could not be the original formulation of the theorem since Noetherian rings were named after Emmy Noether, who lived from 1882 to 1935. Do you know the original formulation of the theorem?
