Remarks on: `Theory of Neutrino Oscillations' (hep-ph/0311241) by C.Giunti, the comments by L.B.Okun et al in hep-ph/0312151, and Giunti's reply in hep-ph/0312180

As pointed out previously, some of the hypotheses used in the standard discussion of the quantum mechanics neutrino oscillations, recently summarised in the paper `Theory of Neutrino Oscillations' by C.Giunti, lack any physical foundation and lead to neglect of both a factor of two correction in the contribution of neutrino propagation to the oscillation phase and an important contribution to the latter from the propagator of the source particle.
