Title: Free particle systems and their dynamics in de Sitter space
Abstract: A first step in determining all the global projective unitary representations describing free particle systems in imaginary Lobachevsky space is made. Essentially we determine explicitly the global form of any representation describing a free particle of spin j on the group generated by rotations and translations of space–time at time t and time translations. We also discuss whether or not positional observables should be preserved under physical equivalence and determine the effects this has on the representation theory of free particle systems.
