Almost positively closed models
Mohammed Belkasmi
We introduce the notions of almost positively closed models and positive strong amalgamation property. We study the fundamental properties of these notions and develop some interac…
Positive Strong Amalgamation
Mohammed Belkasmi
We present the notions of positively complete theory and general forms of amalgamation in the framework of positive logic. We explore the fundamental properties of positively compl…
Algebraically closed structures in Positive Logic
Mohammed Belkasmi
In this paper we extend of the notion of algebraically closed given in the case of groups and skew fields to an arbitrary h-inductive theory. The main subject of this paper is the…
Positive Robinson theories and h-maximal models
M. Belkasmi
In this paper we continue the exploration of the classes of positively closed and h-maximal model of an h-inductive theory in the context of positive logic. In the section 2 we giv…
Positive Amalgamation
Mohammed Belkasmi
We study the amalgamation property in positive logic. We give some connections between the amalgamation property and Robinson theories, model-complete theories and the Hausdorff pr…
Compactness in positive logic
Mohammed Belkasmi
With the aim of developing the concepts of positive logic and in response to a question that was asked by Poizat in one of his articles, I wrote this article. The main topic is the…
