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 physics and control theory. This publication will be a real find for students, graduate students and specialists working in the field of applied mathematics, physics, engineering and related disciplines .. The authors focus on non-smooth operators that play a key role in modeling distributed systems, such as thermal conduction systems. The book offers the reader a unique perspective on complex mathematical concepts, focusing on their practical application. Unlike traditional approaches, models that take into account the features of non-smooth operators are considered here, which allows a more accurate description of the processes occurring in real systems. Readers interested in mathematical modeling, control theory, and physical processes will find many useful ideas and methods in this book. The authors not only explain the theoretical aspects, but also offer practical examples, which makes the material accessible and understandable. The book will be especially useful for those engaged in research in the field of thermal physics, as well as engineers working on projects related to heat transfer and energy. The topics raised in the book cover a wide range of issues, such as thermal conductivity dynamics, system stability, and the influence of non-smooth operators on distributed system behavior. The authors consider in detail mathematical models that allow predicting the behavior of systems under different conditions. This makes the book relevant not only for theorists, but also for practitioners who need to understand how mathematical models can be applied to real-world problems. Style B. N. Kozlova and K. A. Magomedov is distinguished by clarity and logical presentation, which allows the reader to easily follow the course of thought of the authors. Their previous work has also earned recognition in the scientific community, and this book is no exception. The authors are actively involved in research in the field of mathematical physics and control theory, which gives their works special value and relevance. Unsmooth Operators and Distributed Systems . (Heat Conduction Models)” will not only be a useful teaching tool, but also a source of inspiration for those who seek to understand more deeply the complex processes occurring in nature and technology. It opens up new horizons for research and practical application, making it an indispensable tool for students, graduate students and professionals in science and technology.
