Description
A new approach to describe elementary particles in curved space-times will be discussed. Wigner's program is extended by replacing kinematical symmetry groups by its natural generalization to curved space-times: kinematical groupoids. Then, elementary particles are classified according to the irreducible projective representations of the kinematical groupoid of the given space-time. The same background allows to analyse the foundations of relativistic information theory in curved background space-times.
