Abstract: (APS)
The question is analyzed how to describe a closed relativistic system formed by n particlelike constituents. It is proposed that to such a system there corresponds a unitary representation U of the Poincaré group being a function of n(n−1)2 potentials, one for each pair, such that cluster separability holds: If the constituents are grouped into k clusters and the potentials are set to zero between constituents belonging to different clusters, then U factorizes into a tensor product of k representations, any one of them describing a closed system associated with a particular cluster of constituents. An explicit and mathematically rigorous construction is given such that these properties hold.
