let be a Hamiltonian system $ H= H(x,p) $

for this system there is a conserved quantity namely $ C=xp $ so the total system is invariant under rotation

if we 'quantizy' this function $ Cf(x)=\lambda _{n}f(x) $ the result is known and

$ f(x)= Ax^{{1/2}+i\lambda _{n}} $ for some constant 'A'

then how is this function $ f(x) $ related to the quantization of the Hamiltonian

$ H\Psi (x,t)= E_{n}\Psi (x,t) $

for example if the system has a SYMMETRY so there is a conserved quantity (there can be more constants of motion of course) how does this affect to the quantization of the TOTAL hamiltonian ??

Which symmetry gives rise to that conserved quantity? The operator corresponding to that symmetry's generator will commute with the quantized Hamiltonian. – Chay Paterson Jul 20 '13 at 17:39
