Unsmooth Operators and Distributed Systems by B. N. Kozlova and K. A. Magomedov is a fascinating and in-depth study that immerses the reader in the world of modern mathematical methods and their application in the field of distributed systems. This work will be a real discovery for students, graduate students and specialists in mathematics, computer science and engineering, as well as for anyone interested in the theoretical foundations and practical aspects of working with operators and systems. The authors focus on non-smooth operators an important tool in functional space theory and mathematical modeling. The book examines their properties, methods of analysis and application in various fields of science and technology. The authors not only explain the theoretical aspects, but also demonstrate how these concepts can be used to solve real-world problems associated with distributed systems. The reader will be able to see how abstract mathematical ideas find their application in areas such as signal processing, dynamic systems management, and process optimization. The book will be especially interesting for those who are fond of mathematics and its applications in engineering. Students studying applied mathematics, computer science or related disciplines will find in it useful materials for preparing for exams and writing term papers . Specialists in systems analysis and management will also appreciate the deep approach of the authors to the problem. It is important to note that the book is suitable not only for professionals, but also for science lovers who want to expand their knowledge of modern mathematical methods. The topics raised in the book cover a wide range of issues, including sustainability analysis, optimization, management theory, and complex systems modeling. The authors emphasize the importance of non-smooth operators in the context of modern technologies and scientific research, which makes the book relevant and in demand. Readers will be able to learn about new approaches to solving problems that previously seemed insoluble, and see how mathematics can be the key to understanding complex processes. The style of the authors is distinguished by clarity and accessibility of the presentation, which allows even complex mathematical concepts to be perceived easily and with interest. In. N. Kozlov and K. A. Magomedov are experienced researchers and educators who know how to convey complex ideas to the reader without losing depth and accuracy.
