## Main Question or Discussion Point

I'd liked to know whether the postulates of standard QM are still valid in Relativistic QM

By postulates I mean what is ussually stated in texbooks as follows

1)Physical states are determined by a vector in sate space E

2)A measurable physical quantity A is described by an observable A acting on E

3)The possible results in a measurement are the eigenvalues of the corresponding observable

4)The postulate that states the provabilities of the differents possible results

5)Reduction of the wave packet or wave function colapse

6)Schrodinger equation

[tex]i\hbar\frac{d|\psi(t)>}{dt}=H(t)|\psi(t)>[/tex]
