Model-theoretical questions of the Jonsson spectrum
Қарағанды университетінің хабаршысы. Математика сериясы, 2020 In this paper, new concepts are defined in the framework of the study of Jonsson spectrum. We consider a spectrum with respect to the concept of cosemanticness, which is a generalization of elementary equivalence in the class of inductive, generally ...

Model-theoretic properties of semantic pairs and e.f.c.p. in Jonsson spectrum
Қарағанды университетінің хабаршысы. Математика сериясы, 2023 The article is committed to the study of model-theoretic properties of stable hereditary Jonsson theories, wherein we consider Jonsson theories that retain jonssonnes for any permissible enrichment.

Geometry of strongly minimal hybrids of fragments of theoretical sets [PDF]
Қарағанды университетінің хабаршысы. Математика сериясы, 2023 In this article, strongly minimal geometries of fragment hybrids are considered. In this article, a new concept was introduced as a family of Jonsson definable subsets of the semantic model of the Jonsson theory T, denoted by JDef(CT).
