Hey I was hoping you guys could clarify some stuff in Dirac, I'm trying to sort through the Schrodinger representation:
1) What exactly is the standard ket > ? Can anyone give me it in terms of pure linear algebra? What does it mean for it to be unity in terms of wave functions??
2) I guess Schrodinger's representation allows us to use only position and corresponding position derivatives to describe a physical system?
3) When we have the coefficient i in the equation for the quantum Poisson bracket, is this the complex i? Or is it an arbitrary coefficient.
4) When exactly can't we eliminate arbitrary phase factors? I know when the phase factor is a constant, we can take it such that it is unity when it is multiplied by it's conjugate.
