Countable infinite existentially closed models of universally axiomatizable theories

Siberian Advances in Mathematics, 2016
Summary: We obtain a new criterion for a model of a universally axiomatizable theory to be existentially closed. The notion of a maximal existential type is used in the proof and for investigating properties of countable infinite existentially closed structures.

The countable existentially closed pseudocomplemented semilattice

Archive for Mathematical Logic, 2017
As the class $$\mathcal {PCSL}$$PCSL of pseudocomplemented semilattices is a universal Horn class generated by a single finite structure it has a $$\aleph _0$$ℵ0-categorical model companion $$\mathcal {PCSL}^*$$PCSL∗.

Existentially closed models via constructible sets: There are 2^ℵ0 existentially closed pairwise non elementarily equivalent existentially closed ordered groups

Journal of Symbolic Logic, 1996
AbstractWe prove that there are 2χ0 pairwise non elementarily equivalent existentially closed ordered groups, which solve the main open problem in this area (cf. [3, 10]).A simple direct proof is given of the weaker fact that the theory of ordered groups has no model companion; the case of the ordered division rings over a field k is also investigated ...
