Causality as a Casualty of Pregeometry [PDF]
, 2003 In Wheeler’s pregeometry, one attempts to derive properties of the spacetime manifold, such as metric, continuity, dimensionality, topology, locality, symmetry, and causality from an otherwise structureless set [1]. Requardt & Roy refer to this methodologically reductionist attempt to model the properties of spacetime as “bottom up pregeometry” [2]. In

Pregeometry Via Uniform Spaces [PDF]
, 2002 We begin by motivating a pregeometric approach to quantum gravity. A pregeometry is then introduced over denumberable sets which employs the discrete uniform space D X and a uniformity base U B induced by a topological group. The entourages of D X provide a non-metric notion of locality consistent with the open balls of a differentiable manifold ...

Towards BRST quantization of pregeometry and topological pregeometry
Nuclear Physics B, 1993 Abstract We investigate the Dirac bracket algebra of the scalar pregeometry including topological pregeometry with BRST formalism, as the first step to its quantization. We examine unitarity of the S-matrix, derive the precise expression for induced gravity, and discuss how the gravity is induced from the topological theory.

Abstract: "The aim of this paper is to set the foundation to separate geometric model theory from model theory. Our thesis is that it is possible to lift results from geometric model theory to non first order logic (e.g. L[subscript omegaΓéü, omega]).

Classical Relativistic Tests in Zatrikean Pregeometry [PDF]
AIP Conference Proceedings, 2006 Three well-known problems (perihelion advance, photon deflection, radar echo delay) are studied in the framework of Zatrikean Pregeometry. The results differ less than 0.1% from those of General Relativity.

An Attempt at Pregeometry: -- Gravity with Composite Metric -- [PDF]
Progress of Theoretical Physics, 1978 Summary: According to fundamental postulates and the principle of relativity, we derive the basic determinant Lagrangian of `pregeometry', from which geometrodynamics, or Einstein's gravity, is derived. The metric and, therefore, the space-time distance itself appear as composites of lepton-antilepton and quarkantiquark pairs.
