Hilbert's theorem
Theorem. If is a left (resp. right) Noetherian ring, then the polynomial ring is also a left (resp. right) Noetherian ring. Remark. We will give two proofs, in both only the "left" case is considered; the proof for the right case is similar. Suppose is a non-finitely generated left ideal. Then by recursion (using the axiom of dependent ch… WebI have been trying to prove that the propositional formula ( α → ¬ β) → ( ( α → β) → ¬ α) is a theorem in Hilbert's system, i.e., to prove ⊢ ( α → ¬ β) → ( ( α → β) → ¬ α) using the …

In differential geometry, Hilbert's theorem (1901) states that there exists no complete regular surface of constant negative gaussian curvature immersed in . This theorem answers the question for the negative case of which surfaces in can be obtained by isometrically immersing complete manifolds with constant curvature.
WebFoliations of Hilbert modular surfaces Curtis T. McMullen∗ 21 February, 2005 Abstract The Hilbert modular surface XD is the moduli space of Abelian varieties A with real multiplication by a quadratic order of discriminant D > 1. The locus where A is a product of elliptic curves determines a finite union of algebraic curves X Webis complete, we call it a Hilbert space, which is showed in part 3. In part 4, we introduce orthogonal and orthonormal system and introduce the concept of orthonormal basis …
