The book "Non-holonomic dynamical systems", edited by Borisov A. In. and Mamaeva I. C. is a fascinating and in-depth study in the field of dynamical systems theory that will be of interest to both professionals and students seeking to expand their knowledge in this complex but exciting field of science. From the first pages, the reader plunges into a world where the dynamics of systems do not obey the usual laws, and where every movement, every change in the state of the system requires a special approach and understanding. The authors, with a wealth of experience and in-depth knowledge in the field of mechanics and control theory, offer a unique view of non-holonomic systems, which differ from holonomic systems in that their behavior cannot be fully described using simple equations. This creates many interesting challenges and opens up new horizons for research. The book will be especially useful for those interested in mathematical modeling, control theory and applied mechanics. Students and graduate students of technical specialties, as well as researchers working in the field of automation and robotics, will find here a lot of useful materials and examples. Even professionals working in related fields, such as physics or economics, will be able to extract valuable information from the book, since the principles described by the authors have a wide range of applications. The topics raised in the book cover many aspects, ranging from the foundations of dynamical systems theory to complex models that can be used to analyze real-world processes. The authors emphasize the importance of understanding non-holonomic systems in the context of modern technologies and scientific research, which makes the book relevant and in demand in the context of the rapid development of science and technology. The style of presentation of the authors is clear and accessible, which allows the reader to easily assimilate complex concepts and apply them in practice. Borisov A . In. and Mamaev I. C. They are known for their scientific works and publications, and in this book they continue the tradition of high-quality scientific presentation, combining theory with practical examples. Their previous work, such as "Limited System Dynamics" and "Complicated Process Modeling", has also earned recognition in the scientific community and can serve as an excellent addition to the study of topics covered in "Non-holonomic Dynamical Systems" .. The book not only describes theoretical aspects, but also offers the reader practical tasks and examples, making it an ideal teaching aid. It encourages critical thinking and analysis, which is especially important for those who seek not only to acquire knowledge, but also to apply it in real situations. Readers who like to solve puzzles and look for non-standard solutions will find in this book many interesting tasks that will help develop analytical abilities. In conclusion, Nonholonomic Dynamical Systems is not just a book, but a real find for anyone who wants to deepen their knowledge in the field of dynamical systems and their management. It will become a faithful companion for students, researchers and practitioners seeking to master complex concepts and apply them in their activities. If you are looking for literature that combines scientific rigor and practical value, then this work should definitely take its rightful place on your shelf.
