The main topic of this article is the study of the similarity concept of Jonsson's theories. One of the interesting moments of this work is that the presented examples of similarity are considered in different signatures. In the framework of the classification of Jonsson's theories, the concept of similarity in the language of the semantic triple of Jonsson's theory was considered.
A description of the syntactic and semantic similarity of the perfect fragments of the Jonsson subsets of the semantic model of the Jonsson existential-primary convex theory is obtained.

For this, the principle of dynamic programming and the solution of the Hamilton-Jacobi-Bellman equation are applied. In the paper, inverse problems for the stochastic differential equation of the Merton problem with the Wiener process [5] are investigated numerically. Inverse problems consist of determining the function on the right (control function) [6]. The constraint Z(t)0 is necessary to exclude the situation when the investor becomes bankrupt and his debt is refinanced by further loans. The investor invests the fraction of (t) of total wealth held in stock, and the remaining part of.
This means that by small variations of the parameter significant changes are made in the solution of the direct problem.

The relation (1.6) of the spectral parameters rewrites the sequence (1.7) into an unbounded monotonic increasing sequence of Steklov eigenvalues (1.1). V1 and its derivatives are provided, for example, by the general results of the theory of elliptic boundary value problems in domains with angular and canonical points [3], [4]. In the framework of the method of matched asymptotic expansions, we integrate as outer expansions and construct the following inner expansion in uniformly spaced coordinates.

ON THE IMPROVEMENT OF THE CONVERGENCE VALUE ESTIMATION OF THE FIXABLE ZONE METHOD FOR NONLINEAR LIMIT VALUE. The article deals with the problem of solving the approximation of the system of Cauchy-Kovalevskaya equations. A priori estimates are obtained and a generalized solution of the problem using Galerkin's uniqueness method is proved.
One of the problems of computational mathematics is to create effective numerical algorithms for solving nonlinear boundary value problems of mathematical physics in complex domains (with curvilinear boundaries). For example, the finite element method, the method of limit integral equations and the method of fictitious domains. For example, the method of fictional areas allows to significantly increase the degree of automation of programming, which greatly facilitates the transition from one application task to another.
These technological factors of the method of fictitious areas in combination with the method of finite differences are especially valuable when creating the functional filling of application packages. This article is devoted to studying some properties of the solution of problems in the method of fictitious domains for nonlinear elliptic equations.

This article discusses the importance of the new education reform in our country and its implementation in schools. Above all, physics lessons in English encourage students to expand their vocabulary, make new discoveries, and carry out various observations and experiments. We also explain to students that they must use the acquired knowledge to meet their daily needs.
The main thing is that the student will have a vocabulary of English speaking skills, his speaking skills will be created. Solid state physics problem solving is built using Einstein, Debye, Gamma functions using computer. The article describes some of the tasks of pedagogical measurements that we encounter in the practice of universities.
Описание задач и возможных методов их решения важны с точки зрения их обобщения и включения в содержание дисциплин бакалавриата и магистратуры. Приведены примеры формулирования научной темы по актуальной проблеме и новой дисциплине, относящейся к педагогическим измерениям для уровня магистра. Специалисты по образовательным измерениям из многих стран объединены в Международную ассоциацию по оценке образования (МАГАТЭ, www.iaea.info).
Ежегодно МАГАТЭ проводит научные конференции, на которых собираются ведущие специалисты из разных стран для обсуждения актуальных проблем промышленности (www.iaea2018.org).

The organization and implementation of such classes in history, literature, biology, and physics have made particular progress. This situation develops mainly because the teacher does not have special training in the field of substantive use of the potential of the city's socio-cultural environment. When setting the objectives of the informatics lesson in the museum, the teacher relied on the existing knowledge of schoolchildren, interesting facts about the museum object and other facts.
The teacher adhered to the structure of the material, providing an opportunity to remember the basic idea of the lesson. In the context of the digitization of the education system, approaches to teaching computer science, including computer graphics, are undergoing significant changes. As part of the work, the authors are trying to determine the principles of the organization of digital portfolios.
The article considers the model of digitalization of the university - as the basis for the digital transformation of the university. Keywords: digitization, digital transformation of the university, big data, digital analytics, augmented and virtual reality. In the organization of research activities, the function of the teacher changes: he ceases to be the main source of information for students and becomes the organizer of their own cognitive activity.
The main goal of scientific research activity (SRA) is self-realization of the student's personality on the basis of the acquired research skills. Rules for the teacher's work with students in the study The famous specialist in "research training" D. The wording of the theme reflects the coexistence in science of already known and not yet explored, i.e. the process of developing scientific knowledge.
This is a kind of problem carrier that research is directed towards.
