As a simplifying assumption, we consider a scale factor a(t) which oscillates according to a local time and that a(t) > 0 as considered in many nonsingular bouncing cosmology models [7, 10, 13], and that can be expanded in Fourier serie ...

... In UFT333 it is shown that the ECE2 hamiltonian can be quantized using at least four different classification schemes, each leading to different spectral results. The method used by Dirac is a subjective choice of approximation. The schemes in UFT333 are illustrated with rigorous quantization of the ...
