Why Unitary Evolution? QM Justification Ideas

[QUOTE="dextercioby, post: 6845294, member: 1064"] While that is true, it must be said that „Newtonian spacetimes” are substituted for curved spacetimes in GR or spacetimes with curvature and torsion in the Einstein-Cartan version, so that any extension of the known formalism of the PVM/POVM approach to quantum theory is well justified, so I see no reason NOT to go to CPTP maps. Indeed, the „perfect mathematics” which comes from unitarity (I mean all the beautiful functional analytic + Lie groups/algebras theorems) + „unitarity preserves probabilities” seem an ideal combination, but I think it cannot be the whole story. Pinging prof. Arnold Neumaier. I will like to see what he says to you. [USER=293806]@A. Neumaier[/USER] [/QUOTE]
