Introduction to the theory of differential equations

The book contains all the educational material in accordance with the program of the course of differential equations for mechanical-mathematical and physical and mathematical specialties of universities. There is also a small amount of additional material associated with technical applications. This allows you to choose material for lectures depending on the profile of the university. The volume of the book is significantly reduced in comparison with the available textbooks by reducing additional material and choosing simpler evidence from those available in the educational literature.
Theory is presented in sufficient detail and is available for students with an average level of training. Examples of solutions to typical problems are given with explanations. At the end of the paragraphs, the tasks of the tasks for exercises from the collection of tasks on the differential equations" A.F. Filippova (3rd ed. M.: URSS, 2009), and also indicate some theoretical directions adjacent to the issues that are available on which there is Literature in Russian.
For students of physical and mathematical specialties, teachers, as well as specialists in different fields of natural sciences that use mathematics in their work
