Metric Theory of Functions and Related Questions of Analysis . Collection of articles" edited by C. M. Nikolsky and other outstanding specialists, is a unique publication that immerses the reader in the depths of metric theory and analysis. This is not just a collection of articles, but a real treasure trove of knowledge, collected from the works of leading scientists in the field of mathematics, which makes it an indispensable resource for students, graduate students and professionals seeking to deepen their knowledge in this complex but fascinating area. The book covers a wide range of topics related to metric function theory, including basic concepts, methods, and applications. The reader will be able to get acquainted with different approaches to the analysis of functions, their properties and behavior in different metric spaces. Each article in the collection is written in order not only to present theoretical aspects, but also to demonstrate their practical application, which makes the material available and relevant. This book will be especially interesting for those who are fond of mathematical analysis, function theory and related disciplines. Students of mathematical faculties, graduate students, as well as teachers and researchers will find in it many useful ideas and inspirations for their own research. The age category of readers is not limited, however, in the first place, it is aimed at those who already have basic knowledge in mathematics and seek to expand their horizons. Topics raised in the collection range from the basics of metric theory to more complex issues, such as properties of continuous functions, limits, convergence, and more. Each article is an in-depth analysis of a specific problem, which allows the reader not only to assimilate the material, but also to develop critical thinking. The book also touches on important aspects of the application of metric theory in other fields of science, such as physics and economics, which emphasizes its interdisciplinary nature. The writing style of the authors is clear and logical, which makes complex concepts more accessible to understanding. C. M. Nikolsky, as an editor, is known for his ability to present complex ideas in a simple and understandable language. His previous work, such as "
