Spin and entanglement in general relativity

Abstract In a previous paper, we have shown how the classical and quantum relativistic dynamics of Stueckelberg–Horwitz–Piron [SHP] theory can be embedded in general relativity (GR). We briefly review SHP here and, particular, formulation spin framework theory. show embedded, using theorem Abraham, Marsden Ratiu also explicit derivation, into GR by constructing local induced representation. The relation to work Fock Ivanenko is discussed. that gravitational field there highly complex structure for distribution support wave function. then discuss entanglement spins two body system.
