The book "Granical problems of non-local hydrodynamics" under the authorship of Filippov is a fascinating and in-depth study that immerses the reader in the world of complex physical phenomena related to the movement of liquids and gases. This work will be of interest not only to professional physicists and engineers, but also to those who seek to understand how nonlocal interactions affect fluid dynamics in various systems. In his book, Filippov examines the boundary problems that arise in non-local hydrodynamics areas where traditional approaches and methods may be insufficient. It offers the reader a unique perspective on the problems associated with the behavior of fluids at the boundaries of different media, as well as the interaction between them. The book is filled with examples that illustrate theoretical concepts, and offers the reader the opportunity to see how these ideas are applied in practice. One of the key topics raised in the book is the effect of non-local effects on fluid dynamics. Filippov explains how these effects can change the usual ideas about hydrodynamic processes and how they can be taken into account when modeling various systems. The reader will be able to learn about new methods of solving problems that previously seemed unsolvable, and how these solutions can be applied in areas such as ecology, engineering, and even biology. The book will be particularly useful for undergraduate and graduate students studying physics, mechanics, and engineering sciences. It will also attract the attention of researchers working in the field of hydrodynamics and related disciplines who are looking for new approaches and ideas for their projects. Thanks to the accessible style of presentation and clear explanations of complex concepts, readers will be able to easily absorb the material and apply it in their practice. Filippov, as the author, is known for his deep understanding of physics and ability to explain complex ideas in simple and understandable language. His previous works, such as "Fundamentals of Hydrodynamics" and "Models and Methods in Hydrodynamics", have already won recognition among professionals and students. In this book, he continues his tradition by offering readers not only theoretical knowledge, but also practical skills that they can use in their professional activities. Topics raised in the "Granical Problems of Nonlocal Hydrodynamics" cover a wide range of issues, including the interaction of liquids with solids, the effect of temperature and pressure on flow dynamics, and numerical modeling methods. These aspects make the book relevant and in demand in the context of modern scientific and engineering progress. Reading this book will be a real journey into the world of hydrodynamics, where everyone can find something new and useful for themselves. If you are interested in physics, engineering or just want to expand your knowledge of how liquids and gases work, Filippov’s “Granical Problems of Nonlocal Hydrodynamics” is exactly the piece you need. Do not miss the opportunity to immerse yourself in the exciting world of non-local interactions and discover new horizons in the study of hydrodynamics!
