I don't think it requires this assumption.

For the rest, the Gleason theorem really does the heavy lifting. My disatisfaction with the state of the art stems from wanting to derive Schroedinger's equation from something more basic. SE already assumes a complex Hilbert space, from which the rest follows. We do know that the SE is essentially a statement of energy conservation, in the context of a complex Hilbert space. -- ---------------------------------------------------------------------------- Dr Russell Standish Phone 0425 253119 (mobile) Principal, High Performance Coders [email protected] http://www.hpcoders.com.au ---------------------------------------------------------------------------- -- You received this message because you are subscribed to the Google Groups "Everything List" group.
