Unsmooth Operators and Distributed Systems . (Models of thermal conductivity)", written by B. N. Goats and K. A. Magomedov, is a fascinating and in-depth study in mathematical modeling and operator theory. This publication will be a real find for students, graduate students and researchers interested in mathematics, physics and engineering sciences. If you are looking for literature that can expand your knowledge of distributed systems and their application in real-world problems, then this book is for you. On the pages of the book, the authors immerse the reader in the world of non-smooth operators, which play a key role in modeling the processes of heat conduction. They explain how these operators influence the behavior of distributed systems and how they can be used to solve complex problems associated with thermal processes. The book examines various models that allow us to understand how heat spreads in environments with a heterogeneous structure, as well as how various external factors affect this. One of the features of this publication is its accessibility to a wide audience. The authors seek to explain complex concepts in simple and understandable language, which makes the book useful not only for professionals, but also for those who are just starting their way in this field. Readers interested in mathematical modeling, physics and engineering will find many useful ideas and practical applications in the book. The topics raised in the book cover a wide range of issues related to mathematical analysis, operator theory and their application in various fields of science and technology. The authors emphasize the importance of understanding non-smooth operators to solve real-world problems, such as modeling thermal conductivity in complex environments, which makes this book relevant in light of current scientific research and technological developments. The style of the authors is distinguished by clarity and logical presentation, which allows the reader to easily absorb the material. In. N. Kozlov and K. A. Magomedov experienced researchers and teachers who know how to convey complex ideas to the audience Their previous works were also distinguished by a high level of scientific rigor and practical significance, which makes their latest edition especially valuable for readers.
