  4. The conclusions reached in ref. (3). ref. (4)K. Kang:Nuovo Cimento (in press) (1967). Further works done in this area can be found in ref. (2–4) can be summarized as follows; the situation in which one of the two particles with identical quantum numbers is elementary and the other one is composite as defined in the framework of theN/D method is equivalent to the state of two elementary particles with eq. (1) in a full field theory. It is also noted that eq. (1) is symmetric with respect to particles 1 and 2, thus the elementary pole is undistinguishable from the composite pole.

  5. A(s) is related to the scattering amplitudeT(s) byT(s)=n(s)/d(s)+A(s)/d2(s), where the first (second) term is the one-particle irreducible (reducible) part. Detailed discussions on the decomposition are given in ref. (3)..
