The dynamics of binary alternatives for a discrete pregeometry [PDF]
, 2020 A particular case of a causal set is considered that is a directed dyadic acyclic graph. This is a model of a discrete pregeometry on a microscopic scale. The dynamics is a stochastic sequential growth of the graph.

Pregeometry, Formal Language and Constructivist Foundations of Physics [PDF]
, 2023 How does one formalize the structure of structures necessary for the foundations of physics? This work is an attempt at conceptualizing the metaphysics of pregeometric structures, upon which new and existing notions of quantum geometry may find a foun ...

Heritability of types of a pregeometry relative to a family of relational structures
Қарағанды университетінің хабаршысы. Математика сериясыA series of geometrical and topological properties induced by structures, including degeneration, modularity, local modularity, projectivity, local finiteness, etc., play an important role in clarifying structural relationships and in classifying basic ...

Automorphisms, flats and erections of pregeometries
, 1973 We characterize pregeometries in terms of their flats - giving necessary and sufficient conditions for a collection of sets to be the flats of a pregeometry. We begin a systematic study of automorphisms of pregeometries; arguing geometrically, we obtain

Finding a field in a Zariski-like structure [PDF]
, 2017 We show that if M is a Zariski-like structure (see [7]) and the canonical pregeometry obtained from the bounded closure operator (bcl) is non-locally modular, then M interprets either an algebraically closed field or a non-classical group.

The finite submodel property and ω-categorical expansions of pregeometries
, 2006 We prove, by a probabilistic argument, that a class of ω-categorical structures, on which algebraic closure defines a pregeometry, has the finite submodel property. This class includes any expansion of a pure set or of a vector space, projective space or
