The de Sitter-Castelnuovo universe and elementary particle physics

If we study the de Sitter universe in the geodetic representation, we obtain the projective relativity, valid on the cosmic scale, for hyperdense matter and high energies. The new theory can be applied also to quantum and elementary particle physics. In this work we examine the angular momentum operator, the D'Alembertian generalized equation, and study the electron, conceived as an oscillating microuniverse.Work sponsored by GNFM-CNR.
