The purposes of studying the discipline

The purpose of studying the discipline is to train specialists who have the knowledge and skills to use effectively the basic methods of the theory of differential equations to study the phenomena and processes of reality surrounding us.

Studying the discipline solves the following problem:

– acquiring practical skills in solving mathematical problems, constructing and analyzing mathematical models described by differential equations.

As a result of the training, the undergraduate must

   know:

– the basic methods of making up differential models of real phenomena and processes;

– methods for qualitative research of differential models;

– the basic facts of the theory of stability of motion;

     be able to:

 – Practically apply the methods of making up differential models to the construction of specific models from various fields of natural science and technology;

– use methods of a qualitative nature for the study of specific practical problems;

– Solve stability problems by methods of stability theory, both in the case of instantaneous perturbations and in the case of constantly acting perturbations.
