چکیده

We characterise the existentially closed models of theory exponential fields. They do not form an elementary class, but can be studied using positive logic. find amalgamation bases and types over them. define a notion independence show that independent systems higher dimension also amalgamated. extend some notions from classification to logic position category fields in stability hierarchy as NSOP$_1$ TP$_2$.

Existentially closed ordered difference fields and rings

We describe classes of existentially closed ordered difference fields and rings. We show an Ax-Kochen type result for a class of valued ordered difference fields. 1. Existentially closed real-closed difference fields. In the first part of this paper we will consider on one hand difference totally ordered fields, namely totally ordered fields with a distinguished automorphism σ and on the other ...

Real closed exponential fields

In an extended abstract [20], Ressayre considered real closed exponential fields and integer parts that respect the exponential function. He outlined a proof that every real closed exponential field has an exponential integer part. In the present paper, we give a detailed account of Ressayre’s construction. The construction becomes canonical once we fix the real closed exponential field R, a re...

Geometric Characterizations of Existentially Closed Fields with Operators

AD-field is a field with a derivation or a difference-operator, called D. In a suitable language, the theory of D-fields has a modelcompanion, whose axioms need not distinguish the two cases in which D can fall. The geometric concepts involved in describing these axioms can be used to characterize the existentially closed fields with a derivation and a difference-operator; but the class of thes...

Existentially closed CSA-groups

We study existentially closed CSA-groups. We prove that existentially closed CSA-groups without involutions are simple and divisible, and that their maximal abelian subgroups are conjugate. We also prove that every countable CSA-group without involutions embeds into a finitely generated one having the same maximal abelian subgroups, except maybe the infinite cyclic ones. We deduce from this tha...

Existentially Closed Dimension Groups

A partially ordered Abelian group M is algebraically (existentially) closed in a class C M of such structures just in case any finite system of weak inequalities (and negations of weak inequalities), defined over M, is solvable in M if solvable in some N ⊇ M in C. After characterizing existentially closed dimension groups this paper derives amalgamation properties for dimension groups, dimensio...
