The book “Quasiclassical approximation for quantum mechanics equations”, written by famous scientists Pavel Maslov and Mikhail Fedoryuk, is a fascinating and in-depth study in the field of quantum mechanics that will be of interest to both students and professional physicists. This work not only illuminates the theoretical aspects of quasi-classical approximation, but also offers the reader practical tools for its application in various fields of science and technology. The main idea of the book is to show how a quasi-classical approximation can be used to solve complex equations of quantum mechanics. The authors explain in detail how this approximation makes it possible to simplify tasks that at first glance seem insoluble, and how it is related to classical mechanics. The book discusses various methods, such as the Wigner method, which helps to understand the behavior of quantum systems in conditions close to classical ones. The book will be especially useful for undergraduate and graduate students studying physics, as well as for researchers working in the field of theoretical physics and quantum technologies. It is suitable for those who are interested in mathematical methods in physics, as well as for those who want to deepen their knowledge of quantum systems and their behavior. Readers interested in topics such as quantum mechanics, statistical physics, and mathematical physics will find many useful ideas and concepts in this book. The topics raised in the book cover a wide range of issues, from the foundations of quantum mechanics to more complex concepts, such as the interaction of quantum systems with external fields. The authors not only explain the theory, but also give practical examples, which makes the material more accessible and understandable. The book also touches on the philosophical aspects of quantum mechanics, which adds depth and layering to the topics discussed. The style of writing Maslov and Fedoryuk is clear and logical . They skillfully balance between theoretical calculations and practical examples, which makes the text not only informative, but also fascinating. This allows the reader not only to understand complex concepts, but also to see how they are applied in real life. The authors use many illustrations and graphs, which helps to visualize the ideas discussed and facilitates the perception of the material. Pavel Maslov and Mikhail Fedoryuk are recognized specialists in the field of theoretical physics, and their previous works have also been highly appreciated in the scientific community.
