Differential equations. Elsgolts L.E.

l. E. Elsholz is a well -known mathematician who made a great contribution to the study of qualitative methods in variational tasks, as well as in the development of the theory of differential equations.

His pedagogical activity, high lecture skills, tireless propaganda of mathematicians reflected in the textbooks written by him for mathematicians, physicists and engineers.

This book is a classic textbook on differential equations for students of physical and physical and mathematical faculties of universities. It is based on lectures that the author gave over the years at the Physics Faculty of Moscow State University. The book presents an unsurpassed presentation of methods for integrating differential equations with the illustration of the main methods of studying and decisions. Each chapter is equipped with problems for independent solution.

The purpose of this textbook is to contribute to a deep assimilation of the theory with the help of 150 detailed examples and about 200 tasks of different levels of complexity: from simple to the most complex and non -trivial. Most examples have a direct application in physics.

The book will be useful and interesting to those who are just starting to get acquainted with the subject, and those who seek to deepen their knowledge in this area.
