Space-time groups for the lattice

  • Miguel Lorente


In the assumption of a lattice theory in which the continuous limit is not taken, the metric of the discrete space-time should be invariant under integral transformations. Based on local isomorphisms between real forms, a method is proposed in order to find the rational and integral elements of the pseudoorthogonal groups. Besides, the rational and integral trigonometric and hyperbolic functions are constructed on the lattice.
