The book "Equalities of mathematical physics" by A. N. Tihonova and A. A. Samara is not just a textbook, but a real find for everyone who seeks to understand the world of mathematical physics more deeply. This work, written taking into account modern scientific realities, covers a wide range of topics related to equations that describe physical phenomena. If you are a student, graduate student or simply passionate about physics and mathematics, this book will become your reliable companion in the study of complex concepts and methods. From the first pages, the authors immerse the reader in the world of mathematical models, which underlie many physical processes. They explain how mathematical physics equations can be used to describe phenomena such as thermal conductivity, wave processes, and electromagnetic fields. Each section of the book is designed so that the reader can not only learn the theoretical aspects, but also apply them in practice. This makes the book especially valuable for those who want not only to know, but also to be able to apply the knowledge gained. The book will be of interest to both students and teachers, as well as everyone who works in the field of physics, engineering and applied mathematics. If you are looking for literature that will help you prepare for exams, deepen your knowledge or simply expand your horizons, the “Equals of Mathematical Physics” will become your faithful assistant. It is suitable for readers with different levels of training, from beginners to more experienced ones, as the authors carefully explain complex concepts and offer many examples and tasks for independent solution. The topics covered in the book are relevant and important for the modern scientific community. The authors raise questions related not only to the theory, but also to the practical application of equations in various fields of science and technology. They focus on how mathematical models help solve real-world problems, such as optimizing processes, creating new materials, and more. This makes the book not only a textbook, but also a source of inspiration for future research. The style of the authors is clear and accessible, which allows the reader to easily absorb even the most complex topics. A. N. Tihonov and A. A. Samara is not only outstanding scientists, but also experienced teachers who know how to convey information to the audience. Their previous works, such as "Methods of Mathematical Physics" and "Course of Mathematical Analysis", also received recognition and became classics in their field. In The Equations of Mathematical Physics, they continue this tradition by offering readers quality and relevant material.
