Lectures on the theory of ordinary differential equations. Petrovsky I.G.

This book, written by an outstanding domestic mathematician, academician I. G. Petrovsky, is based on a course of lectures that he read at Saratov and Moscow Universities. She successfully withstood several reprints and became classic work on the theory of differential equations. The author did not seek to tell about all departments of the theory of differential equations, but chose several questions, trying to state them as whole and strictly possible. The heads and individual paragraphs are attached to tasks that help consolidate the acquired material. It is recommended for university students, teachers, graduate students and specialists - mathematicians and physicists.
