We study definable sets D of SU-rank 1 in M, where M is a countable homogeneous and simple structure in a language with finite relational vocabulary. Each such D can be seen as a ‘canonically… (More)

In this article we give a classification of the binary, simple, ω−categorical structures with SU−rank 1 and trivial pregeometry. This is done both by showing that they satisfy certain extension… (More)

In this article we give an explicit classification for the countably infinite graphs G which are, for some k, ≥k-homogeneous. It turns out that a ≥k−homogeneous graphM is non-homogeneous if and only… (More)

A homogenizable structure $$\mathcal {M}$$M is a structure where we may add a finite number of new relational symbols to represent some $$\emptyset-$$∅-definable relations in order to make the… (More)

We study nite l-colourable structures with an underlying pregeometry. The probability measure that is used corresponds to a process of generating such structures (with a given underlying pregeometry)… (More)

Model theory and combinatorial pregeometries are closely related through the so called algebraic closure operator on strongly minimal sets. The study of projective and affine pregeometries are… (More)
