An algebra of the central types of the mutually model-consistent fragments
Қарағанды университетінің хабаршысы. Математика сериясы, 2021 In this paper, the model-theoretical properties of the algebra of central types of mutually model-consistent fragments are considered. Also, the connections between the center and the Jonsson theory in the permissible signature enrichment are shown, and

On Robinson spectrum of the semantic Jonsson quasivariety of unars [PDF]
Қарағанды университетінің хабаршысы. Математика сериясы, 2023 Given article is devoted to the study of semantic Jonsson quasivariety of universal unars of signature containing only unary functional symbol. The first section of the article consists of basic necessary concepts.

Properties of hybrids of Jonsson theories
BULLETIN OF THE KARAGANDA UNIVERSITY-MATHEMATICS, 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. The main goal of this paper is to study the model-theoretic properties of companions of hybrids of Jonsson theories.

Syntactic similarity of definable closures of Jonsson sets
Қарағанды университетінің хабаршысы. Математика сериясы, 2018 In the framework of the classification of the Jonsson theories concept of interpretability and admissibility in the language of the semantic triple of the Jonsson theory was considered.

Uniform K-stability, Duistermaat-Heckman measures and singularities of pairs [PDF]
, 2016 The purpose of the present paper is to set up a formalism inspired from non-Archimedean geometry to study K-stability. We first provide a detailed analysis of Duistermaat-Heckman measures in the context of test configurations, characterizing in ...

The admissibility and similarity of Jonsson theories
BULLETIN OF THE KARAGANDA UNIVERSITY-MATHEMATICS, 2018 This work is related to the concepts of admissibility, interpretability, syntactic similarity and semantic similarity of Jonsson’s theories.This new concept generalize the notion of syntactic and semantic similarities for Jonsson theories. In the frame of study of preservation of the definable formulas subsets of Jonsson theory’s semantic model ...

The spectral dimension of random brushes [PDF]
, 2007 We consider a class of random graphs, called random brushes, which are constructed by adding linear graphs of random lengths to the vertices of Z^d viewed as a graph. We prove that for d=2 all random brushes have spectral dimension d_s=2. For d=3 we have

Small models of hybrids for special subclasses of Jonsson theories
BULLETIN OF THE KARAGANDA UNIVERSITY-MATHEMATICS, 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. Further, we consider fragments of these sets and create a hybrid of these fragments from them.

A variational approach to the Yau-Tian-Donaldson conjecture
, 2020 We give a variational proof of a version of the Yau-Tian-Donaldson conjecture for twisted K\"ahler-Einstein currents, and use this to express the greatest (twisted) Ricci lower bound in terms of a purely algebro-geometric stability threshold.
