This theorem answers the question for the negative case of which surfaces in can be obtained by isometrically immersing complete manifolds with constant curvature.

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. WebA Hilbert space is an inner product space whose associated metric is complete. That is, a Hilbert space is an inner product space that is also a Banach space. For example, Rn is a …
