The book "Different grids and coordinate transformations for singularly perturbed problems" by B. D. Liseykin and his co-authors is a unique work that opens the door to the world of mathematical modeling and numerical methods used to solve complex problems. Unlike many other scientific publications, this book combines both theoretical foundations and practical aspects, making it an indispensable tool for students, graduate students and specialists in the field of applied mathematics, physics and engineering. The main theme of the book is the difference grids and their application in solving singularly perturbed problems. These problems arise in various fields of science and technology, such as mechanics, thermodynamics and biology, and require a special approach due to the presence of small parameters that can significantly affect the behavior of decisions. The authors offer the reader an in-depth understanding of methods that allow them to effectively cope with such problems, and share their experiences and research that can be useful for both theorists and practitioners. The book will be of interest to a wide range of readers: from senior students to experienced researchers. If you study numerical methods, mathematical modeling or applied sciences, then this publication will become a valuable source of knowledge for you. It will also be useful to engineers and practitioners working in areas related to the modeling of physical processes. Readers interested in modern approaches to solving complex mathematical problems will find in this book many useful ideas and techniques. The topics raised in the book cover a wide range of issues: from the theory of difference schemes to practical examples of their application. The authors consider in detail how to choose the correct difference grids for various tasks, how to carry out coordinate transformations and how to minimize the errors that arise in the numerical solution. This makes the book not only a tutorial, but also a practical guide for those who face real challenges in their work. Style B. D. Liseykin and his co-authors are distinguished by clarity and accessibility of presentation, which allows the reader to easily assimilate complex concepts. The authors use many illustrations and examples, which makes the material more clear and understandable. This is especially important for readers who may not have deep mathematical knowledge, but seek to understand the topic. The book also includes tasks to solve independently, which contributes to a deeper understanding of the material. If you are looking for literature that combines theory and practice, and also offers fresh perspectives on solving singularly perturbed problems, then "Different grids and coordinate transformations for singularly perturbed problems" is exactly what you need. This publication will become a reliable companion in your scientific and professional path, opening new horizons in understanding complex mathematical processes. Do not miss the opportunity to enrich your knowledge and skills with this unique work!
