Tensor and spin representations of SO(4) and discrete quantum gravity
M. Lorente, P. Kramer
Starting from the defining transformations of complex matrices for the SO(4) group, we construct the fundamental representation and the tensor and spinor representations of the gro…
Exact solutions of the Dirac equation and induced representations of the Poincare group on the lattice
M. Lorente
We deduce the structure of the Dirac field on the lattice from the discrete version of differential geometry and from the representation of the integral Lorentz transformations. Th…
Representations of classical groups on the lattice and its application to the field theory on discrete space-time
M. Lorente
We explore the mathematical consequences of the assumption of a discrete space-time. The fundamental laws of physics have to be translated into the language of discrete mathematics…
Creation and Annihilation Operators for Orthogonal Polynomials of Continuous and Discrete Variables
M. Lorente
We develop general expressions for the raising and lowering operators that belong to the orthogonal polynomials of hypergeometric type with discrete and continuous variable. We con…
