Hilbert uniqueness theorem

The second axiom, which is reminiscent of Mach s principle, also contains the seeds of Leibniz s Monads [reschQl]. All is process. That is to say, there is no thing in the universe. Things, objects, entities, are abstractions of what is relatively constant from a process of movement and transformation. They are like the shapes that children like to see in the clouds. The Einstein-Podolsky-Rosen correlations (see section 12.7.1) remind us that what we empirically accept as fundamental particles - electrons, atoms, molecules, etc. - actually never exist in total isolation. Moreover, recalling von Neumann s uniqueness theorem for canonical commutation relations (which asserts that for locally compact phase spaces all Hilbert-space representations of the canonical commutation relations are physically equivalent), we note that for systems with non-locally-compact phase spaces, the uniqueness theorem fails, and therefore there must be infinitely many physically inequivalent and... 

Theorem 1.23. If A V V is a linear, self-conjugate, strongly monotonous and Lipschitz continuous operator in a Hilbert space V, then there exists a unique solution u G K of the variational inequality (1.126) given by the formula... 

Theorem 19 Let L be an absolutely positively determined (APD) linear continuous operator, acting in a complex Hilbert space M. Then the solution of the linear operator equation (4-6) exists and is unique in M, and the minimal residual method, based on the recursive formulae (4-V and (4-13), converges to this solution for any initial approximation mo... 

C est une des variantes du "thEorEme 90" de Hilbert. On notera que eet EnoncE n est plus vrai en gEnEral pour un groupe tel que, ou pour une "forme tordue" de G par example 1 unique forme tordue de G sur le corps S des rEels donne un groups de 1-cohomologie Egal E 2/2Z. ...
