On lattice of existential formulas for fragment of Jonsson set

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2015
This paper its content associated with the study of model - theoretic properties of Jonsson theories and their semantic models. In particular, considering Jonsson sets concerning of their definable circuit described fragments and their relationship to ...

The Triple Helix Perspective of Innovation Systems

open access: yes, 2010
Alongside the neo-institutional model of networked relations among universities, industries, and governments, the Triple Helix can be provided with a neo-evolutionary interpretation as three selection environments operating upon one another: markets ...

On closure operators of Jonsson sets

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы
The 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

Random trees with superexponential branching weights

open access: yes, 2011
We study rooted planar random trees with a probability distribution which is proportional to a product of weight factors $w_n$ associated to the vertices of the tree and depending only on their individual degrees $n$.

Between the LIL and the LSL

open access: yes, 2010
In two earlier papers, two of the present authors (A.G. and U.S.) extended Lai's [Ann. Probab. 2 (1974) 432--440] law of the single logarithm for delayed sums to a multiindex setting in which the edges of the $\mathbf{n}$th window grow like $|\mathbf {n}|

The property of independence for Jonsson sets

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2016
The studies carried out in this article are connected with the description of model - theoretic properties of some, generally speaking, incomplete classes of theories that make a subclass of inductive theories.

Quantum phases of supersymmetric lattice models

open access: yes, 2009
We review recent results on lattice models for spin-less fermions with strong repulsive interactions. A judicious tuning of kinetic and interaction terms leads to a model possessing supersymmetry.

The properties of central types with respect to enrichment by Jonsson set

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2017
The main results of the article are for a new class of theories, namely existential prime strongly convex Jonsson theories. This class is quite broad in terms of algebra, for example it includes the class of all Abelian groups and groups.

The atomic definable subsets of semantic model

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2019
In this paper some properties of small models, generally speaking, not necessarily complete theories and their relationship with each other were considered.

About central types and the cosemanticness of the ∆-PM fragment of the Jonsson set

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2017
This article is concerned with the enrichment of the signature. In own time, when studying the stability of the theory and the concept of an elementary pair of models, Mustafin T.G.
