AP09259295 On the algebraic and definable closures in new strongly minimal theories

Scientific adviser – Verbovsky Victor Valerievich


The solution of the issues under consideration will make it possible to obtain new qualitative results in model theory. Also, the implementation of the tasks will make it possible to introduce new scientific mathematical areas in Kazakhstan, through the introduction of special master's and doctoral courses into the curricula.

The research results will be published in international ranking scientific journals. Solving the problems posed in the project will contribute to the development of both national and international mathematical science and its applications.

Objective of the project

The goal of the project is to study the properties of algebraic and definable closures in new strongly minimal theories, including the development of Galois theory in these theories.

Expected results:

- We will construct functions of two independent variables, definable in some new strongly minimal theories;

- We will find conditions, including conditions for the function mu, guaranteeing that there is no function of two independent variables that can be defined in new strongly minimal theories.

- We will find conditions, including conditions for the function mu, guaranteeing that there is no symmetric function of two independent variables that can be defined in new strongly minimal theories

- We will get a description of new strongly minimal theories that do not allow the elimination of imaginary elements.

- We will find conditions, including on the function mu, guaranteeing that there is no definable function of n independent variables.

- We will describe the structure of algebraic closure in new strongly minimal theories.

Results achieved:

The results of the work and their novelty: for the first time in the history of the Kazakhstan architectural school, the model of a specialist architect of the XXI century was formulated and justified, recommendations for adjusting educational programs for the training of architects in Kazakhstan, modern methods of teaching architects at the undergraduate level.
