The book "Selected sections of the course Vector analysis (theory and examples)", written by the author's team of Logins, Miroshin and Selivanov, is a unique manual that will become an indispensable assistant for students, graduate students and anyone interested in mathematics and its applications . Vector analysis is one of the key disciplines in mathematics, which is widely used in physics, engineering and other sciences. This book offers not only theoretical foundations, but also practical examples, which makes it especially valuable for a deep understanding of the subject. The book discusses the basic concepts and methods of vector analysis, such as vector fields, gradient, divergence and rotor. The authors seek to explain complex ideas in simple and accessible language, which allows the reader to easily digest the material. Each topic is accompanied by examples that illustrate the application of the theory in practice. This makes the book not only a textbook, but also a practical guide that will help the reader to understand the real problems encountered in scientific and engineering activities. Who can like this edition? First of all, it will be useful for students of technical and natural science specialties who study vector analysis as part of their program. However, interest in the book can be shown by a wider range of readers: from schoolchildren preparing for exams to professionals working in the field of physics, mechanics and computer science. If you are looking to deepen your knowledge in mathematics or want to refresh your skills, this tutorial will be an excellent choice. The topics raised in the book go beyond purely mathematical concepts. The authors focus on the connection of vector analysis with real problems, which allows the reader to see how abstract mathematical ideas can be applied to solve specific problems. This makes the book especially relevant in the modern world, where science and technology are rapidly developing, and knowledge of vector analysis becomes necessary for a successful career in various fields. The style of the authors is distinguished by the clarity and logic of the presentation .
