A discrete curvature on a planar graph
M. Lorente
Given a planar graph derived from a spherical, euclidean or hyperbolic tessellation, one can define a discrete curvature by combinatorial properties, which after embedding the grap…
Discrete quantum gravity: the Lorentz invariant weight for the Barrett-Crane model
M. Lorente
In a recent paper [1] we have constructed the spin and tensor representations of SO(4) from which the invariant weight can be derived for the Barrett-Crane model in quantum gravity…
Orthogonal polynomials of several discrete variables and the 3nj-Wigner symbols: applications to spin networks
M. Lorente
The use of orthogonal polynomials for integral models on the lattice is applied to the 3nj-symbols that appear in the coupling of several angular momenta. These symbols are connect…
Orthogonal polynomials, special functions and mathematical physics
M. Lorente
In the 6th Int. Symposium on OPSFA there were several communications dealing with concrete applications of orthogonal polynomials to experimental and theoretical physics, chemistry…
Integrable systems on the lattice and orthogonal polynomials of discrete variable
M. Lorente
Some particular examples of classical and quantum systems on the lattice are solved with the help of orthogonal polynomials and its connection to continuous models are explored.
Some Integrable Quantum Systems on the Lattice
M. Lorente
The Weyl relations, the harmonic oscillator, the hydrogen atom, the Dirac equation on the lattice are presented with the help of the difference equations and the orthogonal polynom…
