 In the equations formula_37 the presence of matter results only in the change of relations imposed on their constituent coordinate functions.The fact that ε becomes infinite by the law confirms that in the solution to one deals with a physical singularity at any values of the powers "p"1, "p"2, "p"3 excepting only (0, 0, 1).For these last values, the singularity is non-physical and can be removed by a change of reference frame.
