Model-theoretic properties of J-superstable Jonsson theories in classes defined by cosemanticness
Қарағанды университетінің хабаршысы. Математика сериясыThis article deals with the problems of model-theoretic characterization of J-superstable Jonsson theories. The characteristic features of such theories are analyzed in terms of J-stability, J-P-superstability, and J-nonmultidimensionality.

Connection of Jonsson theory with some Jonsson polygons theories
Қарағанды университетінің хабаршысы. Математика сериясы, 2019 This article presents the result related to the model - theoretic properties of special subsets of the semantic model of some fixed Jonsson theory. The specialty of these sets is due to their definability and closure.
