Article title: APPLICATION OF MATHEMATICAL METHODS IN THE STUDY OF ECONOMIC MODELSAuthor: Dakasheva Tanzila Muhtarovna
Annotation:
This article discusses the ways of applying mathematical methods in the study of economic processes. The economic meaning of such a mathematical category as a derivative is considered, its meaning and ways of application in solving economic problems are studied. Several economic models are used
as examples.

Article title: TOTAL LEAST SQUARES FOR ESTIMATION OF THE GROSS OUTPUT VECTORAuthor: Ivanov Dmitriy Vladimirovich
Annotation:
The article proposes the estimation of the gross output vector in the presence of errors in the matrix
of direct costs and the final consumption vector. The article suggests the use of the total least squares
method for estimating the gross output vector. Test cases showed that the accuracy of the proposed
estimates of the gross output vector is higher than the accuracy of the estimates obtained using the classical least squares method (OLS).

Article title: APPLICATION OF THE INTEGRAL FOR THE TASKS OF ANALYTICAL AND PROGNOTIC CHARACTER IN THE ECONOMYAuthor: Makarov Sergey Ivanovich, Kurganova Maria Vladimirovna
Annotation:
The relevance of the topic of this work is determined by the fact that the use of integrals allows us
to solve a large number of economic problems. The development and use of economic and mathematical
models indicate the ways of improving economic information oriented to solving a particular system of
planning and management problems.

Article title: CYCLING WHEN SOLVING LINEAR PROGRAMMING PROBLEMSAuthor: Nemudrova Alyona Aleksandrovna
Annotation:
Currently, there is a strong push in the field of scientific and technological progress in our country,
which is closely related to the use of various mathematical methods and computer technology. Special attention should be paid to their use in solving any economic and engineering problems. They, in turn, are
used in many areas of the company's activities, for example, when solving certain problems of planning
and managing production processes, and long-term planning. In this regard, it is important for students of
various fields of higher education to know and understand the application of mathematical methods and
the problems that arise.

Article title: APPLICATION OF THE APPARATUS OF DIFFERENTIAL EQUATIONS IN MODELING OF ECONOMIC PROCESSESAuthor: Nyikina Elena Yuryevna
Annotation:
The aim of this work is to consider some of the techniques of basic mathematical modeling of economic and social processes. The application of the apparatus of differential equations makes it possible to
find an approach to solving many economic problems. The author indicates that the considered method of
mathematical modeling gives a somewhat simplified approach to the compilation of an economicmathematical model. But at the same time, it is noted that there are many mathematical techniques that
allow us to solve more complex problems with multi-purpose problems.

Article title: PROBLEM S5 FOR THE THIRD-ORDER HYPERBOLIC EGUATION IN A THREE-DIMENSIONAL SPACEAuthor: Rodionova Irina Nikolaevna, Sevastyanova Svetlana Alexandrovna
Annotation:
The article presents a method for solving the boundary value for the complete equation of the thirdorder hyperbolic type with variable coefficients. The solution to the problem posed is based on the solution of the Darboux problem in a special class of functions obtained by the authors. The problem is reduced to a set of uniquely solvable Volterra integral equations, by virtue of which its solution can be obtained in explicit form.
