A covariant causal set approach to discrete quantum gravity
Stan Gudder
A covariant causal set (c-causet) is a causal set that is invariant under labeling. Such causets are well-behaved and have a rigid geometry that is determined by a sequence of posi…
An Approach to Discrete Quantum Gravity
Stan Gudder
This article presents a simplified version of the author's previous work. We first construct a causal growth process (CGP). We then form path Hilbert spaces using paths of varying…
Effects as functions on projective Hilbert space
P. Busch, S. P. Gudder
The set of effect operators in a complex Hilbert space can be injectively embedded into the set of functions from the set of one-dimensional projections to the real interval [0,1].…
Compatibility for Probabilistic Theories
Stan Gudder
We define an index of compatibility for a probabilistic theory (PT). Quantum mechanics with index 0 and classical probability theory with index 1 are at the two extremes. In this w…
A Dynamics for Discrete Quantum Gravity
Stan Gudder
This paper is based on the causal set approach to discrete quantum gravity. We first describe a classical sequential growth process (CSGP) in which the universe grows one element a…
