PACS number(s): 04.70.Dy, 04.60.Ds, 99.10.+g (1) The assertion immediately following Eq.( 3) is incorrect.It should be replaced by the following.The fact that B is fixed for the complete spacetime whereas it remains arbitrary for the wedge has a quantum mechanical origin.Different choices of B for the wedge correspond just to different ways of normalizing the wave function.On the other hand the action for the complete spacetime yields upon path integration the partition function which, being the trace of the propagating amplitude, is independent of the inner product used for the wave functionals.(2) Equation ( 19) and the comment immediately following it should read I = I~+ B -vrA(p+) -B - ~A One may take for convenience B = nA(r+) for the wedge, in order to have an action that difFers &om IH only by a surface term at inanity.However, as explained before, this is not mandatory.
