    Quelques Propriétés Des Théories de Jonsson.Yerulan Mustafin - 2002 - Journal of Symbolic Logic 67 (2):528-536.
    On étudie les propriétés des théories de Jonsson et des conditions nécessaires afin que des théories soient de Jonsson; on caractérise les théories de Jonsson cosémantiques c'est-à-dire ayant un modèle homogène universel commun ainsi que certaines théories complètes contenant des théories de Jonsson. On donne des exemples de certaines situations.

  2. Polygones.Tolende G. Mustafin & Bruno Poizat - 1995 - Mathematical Logic Quarterly 41 (1):93-110.
    We study the class of structures formed by all the polygons over a given monoid, which is equivalent to the study of the varieties in a language containing only unary functions. We collect and amplify previous results concerning their stability and superstability. Then we characterize the regular monoids for which all these polygons are ω-stable; the question about the existence of a non regular monoid with this property is left open.

  4. On Superstable CSA-Groups.Abderezak Ould Houcine - 2008 - Annals of Pure and Applied Logic 154 (1):1-7.
    We prove that a nonabelian superstable CSA-group has an infinite definable simple subgroup all of whose proper definable subgroups are abelian. This imply in particular that the existence of nonabelian CSA-group of finite Morley rank is equivalent to the existence of a simple bad group all whose definable proper subgroups are abelian. We give a new proof of a result of Mustafin and Poizat [E. Mustafin, B. Poizat, Sous-groupes superstables de SL2 ] which states that a superstable model (...)
