On closure operators of Jonsson sets [PDF]
Қарағанды университетінің хабаршысы. Математика сериясыThe work is related to the study of the model-theoretic properties of Jonsson theories, which, generally speaking, are not complete. In the article, on the Boolean of Jonsson subsets of the semantic model of some fixed Jonsson theory, the concept of the

Small models of hybrids for special subclasses of Jonsson 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.

Independence relations for exponential fields [PDF]
, 2023 We give four different independence relations on any exponential field. Each is a canonical independence relation on a suitable Abstract Elementary Class of exponential fields, showing that two of these are NSOP$_1$-like and non-simple, a third is stable,

The constructivist’s programme and the problem of pregeometry [PDF]
, 2021 Prominently, Norton (2008) argues against constructivism about spacetime theories, the doctrine that spatiotemporal structure in the dynamics only has derivative status.

Properties of hybrids of Jonsson theories
Қарағанды университетінің хабаршысы. Математика сериясы, 2018 This work is an introduction to the study of the properties of a new concept, as a hybrid of Jonsson theories. We define the basic concepts and framework for studying the model-theoretic properties of these concepts.

Truncations of principal geometries [PDF]
, 1975 We investigate the class of principal pregeometries (free simplicial geometries with spanning simplex) which form an important subclass of the class of transversal pregeometries (free simplicial geometries). We give a coordinate-free method for imbedding

Heritability of Types of Pregeometry with Respect to Compositions of Structures
Известия Иркутского государственного университета: Серия "Математика"In this paper, we investigate how the pregeometry arising from the composition of two predicate signature structures inherits the types of pregeometries of the original stuctures.

GENERIC EXPANSIONS OF NATP THEORIES (Model theoretic aspects of the notion of independence and dimension) [PDF]
, 2023 We show that adding a generic predicate P to an NATP theory preserves NATP, with the assumption of modular pregeometry and elimination of quantifiers and ∃

Normality and superperfection of Jonsson spectra
Қарағанды университетінің хабаршысы. Математика сериясыThis paper investigates the structural properties of Jonsson spectra with respect to the notions of KTnormality, cl-normality, and superperfection. Particular attention is paid to the role of the Kaiser class KT as an internal structural layer of a ...

Exponential algebraicity in exponential fields [PDF]
, 2010 The exponential algebraic closure operator in an exponential field is always a pregeometry and its dimension function satisfies a weak Schanuel property.
