Abstract : The direct product of many irreducible representations of the Poincare group is discussed. A procedure is suggested for the decomposition in the canonical scheme, which is not an iteration of the 2particles method. Also, it is independent of the c.m.s. Corresponding expression for Smatrix elements of many particle processes is given. The properties of the invariant functions associated with elastic scattering in case of parity, time reversal and crossing symmetries is discussed, as well as in case of identical particles. (Author)
