The book "Differential Equations" by the authors Tikhonov A. N. , Vasilieva A. B. and Sweshnikova A. G. is an in-depth and systematic study of one of the key topics in mathematics and its applications. This publication will become an indispensable assistant for students, graduate students, as well as anyone interested in mathematical analysis and its practical aspects. The book focuses on differential equations - the most important tools for describing dynamic processes in a variety of fields: from physics and engineering to biology and economics. The authors aim not only to present theoretical foundations, but also to demonstrate how these equations are applied to solve real-world problems. The book covers a wide range of topics, ranging from the simplest ordinary differential equations to more complex systems, including partial differential equations. Readers who already have a basic knowledge of mathematics will find in this edition not only a theory, but also many examples, problems and practical applications, which makes it especially valuable for those who want to deepen their knowledge and skills in this area. The book will be of interest to students of mathematical and technical specialties, as well as teachers who are looking for high-quality educational material for their courses. The topics raised in Differential Equations cover both classical methods of solution and modern approaches, including numerical methods and computer modeling. The authors emphasize the importance of understanding not only the equations themselves, but also their physical meaning, which allows the reader to see the relationship between abstract mathematics and real phenomena. This makes the book especially valuable for those who seek to apply mathematics in their professional activities. The style of the authors is distinguished by clarity and accessibility of the presentation . They use many illustrations and graphs, which helps to better understand the material and visualize complex concepts. Tikhonov, Vasilyev and Sveshnikov are recognized experts in their fields, and their experience and knowledge make this book a reliable source of information. In addition to the "Differential Equations", they are also the authors of other well-known textbooks and scientific papers, which confirms their high level of professionalism and deep understanding of the subject. The book “Differential Equations” will be an excellent choice for those who are looking for not just a textbook, but a full-fledged guide to studying one of the most fascinating and complex topics in mathematics. It is suitable for both self-study and for use in training courses. If you are interested in mathematics, physics, engineering or related sciences, this publication should definitely take a worthy place in your library.
