Method of the rheostat for studying properties of fragments of theoretical sets

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2020
In this article discusses the model-theoretical properties of fragments of theoretical sets and the rheostat method. These two concepts: theoretical set and rheostat are new. The study of this topic in the framework of the study of Jonsson theories, the

An algebra of the central types of the mutually model-consistent fragments

open access: yesҚарағанды 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

Small models of convex fragments of definable subsets

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2020
This article discusses the problems of that part of Model Theory that studies the properties of countable models of inductive theories with additional properties, or, in other words, Jonsson theories.

Another bijection between $2$-triangulations and pairs of non-crossing Dyck paths [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2009
A $k$-triangulation of the $n$-gon is a maximal set of diagonals of the $n$-gon containing no subset of $k+1$ mutually crossing diagonals. The number of $k$-triangulations of the $n$-gon, determined by Jakob Jonsson, is equal to a $k \times k$ Hankel ...

Companions of the fragments in the Jonsson enrichment

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2017
In this article we consider the properties of central types for the existentially prime strongly convex Jonsson theories in some extension. This class of theories is a subclass of a broad class of Jonsson theories.

Double factorization of the Jonsson spectrum

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы
First of all, we have to note that in this article, we introduced the new concepts of relations between Jonsson theories in the class of cosemanticness for some considered Jonsson spectrum.
