Abstract
A classification has been obtained of the states of a relativistic quantum system. The irreducible representations of an inhomogeneous Lorentz group are divided into four hasic classes P/sub m/,P/sub II/, P/sub o/, O/sub o/. All representations o f classes P/sub m/, P/sub II/, both unitary and non- unitary, are obtained in the explicit form. (tr-auth)
