Geometries on partially ordered sets [PDF]
, 1980 Geometries on finite partially ordered sets extend the concept of matroids on finite sets to partially ordered sets. Geometries are defined in terms of closure operators on partially ordered sets.

Groups with locally modular homogeneous pregeometries are commutative [PDF]
Proceedings of the American Mathematical Society, 2017 It is well known that strongly minimal groups are commutative. Whether this is true for various generalisations of strong minimality has been asked in several different settings. In this note we show that the answer is positive for groups with locally modular homogeneous pregeometries.

Finding groups in Zariski-like structures [PDF]
, 2014 We study quasiminimal classes, i.e. abstract elementary classes (AECs) that arise from a quasiminimal pregeometry structure. For these classes, we develop an independence notion, and in particular, a theory of independence in $M^{eq}$.

Steps toward an axiomatic pregeometry of spacetime [PDF]
, 1998 We present a deductive theory of space-time which is realistic, objective, and relational. It is realistic because it assumes the existence of physical things endowed with concrete properties.

Parthood and Convexity as the Basic Notions of a Theory of Space [PDF]
, 2015 A deductive system of geometry is presented which is based on atomistic mereology ("mereology with points'') and the notion of convexity. The system is formulated in a liberal many-sorted logic which makes use of class-theoretic notions without however ...

Local and global properties of the world [PDF]
, 1997 The essence of the method of physics is inseparably connected with the problem of interplay between local and global properties of the universe. In the present paper we discuss this interplay as it is present in three major departments of contemporary ...
