Topological pregauge-pregeometry
Physics Letters B, 1991 Abstract The pregauge-pregeometric action, i.e. the fundamental matter action whose quantum fluctuations give rise to the Einstein-Hilbert and the Yang-Mills actions, is investigated from the point of view of the topological field theory. We show that the scalar pregauge-pregeometric action is a topological invariant for appropriate choices of the ...

Pregeometry on the subsets of Jonsson theory’s semantic model
Қарағанды университетінің хабаршысы. Математика сериясы, 2018 One of the interesting achievements among investigations from modern model theory is the implement of local properties of the geometry of strongly minimal sets. In E.

Central types of convex fragments of the perfect Jonsson theory
Қарағанды университетінің хабаршысы. Математика сериясы, 2019 In this paper, the central types of convex fragments of the perfect Jonsson theory are considered. The main goal of this paper is to redefine the A.D.

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.

A note on the axioms for Zilber's pseudo-exponential fields [PDF]
, 2011 We show that Zilber's conjecture that complex exponentiation is isomorphic to his pseudo-exponentiation follows from the a priori simpler conjecture that they are elementarily equivalent.

The theory of the exponential differential equations of semiabelian varieties [PDF]
, 2009 The complete first order theories of the exponential differential equations of semiabelian varieties are given. It is shown that these theories also arises from an amalgamation-with-predimension construction in the style of Hrushovski.

Simple structures axiomatized by almost sure theories
, 2015 In this article we give a classification of the binary, simple, $\omega$-categorical structures with SU-rank 1 and trivial pregeometry. This is done both by showing that they satisfy certain extension properties, but also by noting that they may be ...

Independence in computable algebra [PDF]
, 2015 We give a sufficient condition for an algebraic structure to have a computable presentation with a computable basis and a computable presentation with no computable basis.

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.
