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…
Modern theories of discrete time
M. Lorente
We review some modern theories about the structure of space and time, in particular those related to discrete space and time. Following an epistemological method we start from theo…
Quantum process and the foundation of relational theories of space-time
M. Lorente
We present current theories about the structure of space and time, where the building blocks are some fundamental entities (yes-no experiment, quantum processes, spin net-work, pre…
