Cosmology from pregeometry [PDF]
Physical Review D, 2021 We discuss cosmological solutions for a diffeomorphism invariant gauge theory of the non-compact Lorentz group $SO(1,3)$. Besides the gauge bosons our model of pregeometry contains a vector field in the vector representation of $SO(1,3)$ and a scalar singlet.

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.

Algebra Universalis, 1998
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]).

Finite temperature spinor pregeometry [PDF]
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 1983 We obtain the Einstein and Yang-Mills actions as induced actions. Free fermion fields are considered as the only fundamental pregeometric objects. We study in detail the temperature behaviour of the induced Newton and gauge coupling constants. Both of them are seen to decrease as the temperature grows.

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.

Spinor Pregeometry at Finite Tempereture [PDF]
Progress of Theoretical Physics, 1987 We derive the effective action for gravity at finite temperature in spinor pregeometry. The temperature-dependent effective potential for the vierbein which is parametrized as ekp = b diag (1, p, p, p) has the minimum at b=O for fixed p, and behaves asp3 for fixed b. These results indicate that the system of fundamental matters in spinor pregeometry is

Pregeometry and an Extended String Action [PDF]
Progress of Theoretical Physics, 1988 On propose une action de couche d'univers pour une corde transversalement etendue. C'est celle d'une theorie gravitationnelle et de jauge avec des champs de matiere sur la couche d'univers, avec des effets additionnels de la seconde quantite ...
