The book "Geometric inequalities and tasks to a maximum and minimum", written by the author's team as part of D. About. Shklyarsky, N. N. Chentsova and I. M. Jagloma is a unique publication that will become an indispensable tool for students, teachers and anyone interested in mathematics at a deeper level. This work immerses the reader in the world of geometry, revealing not only theoretical aspects, but also practical applications, which makes it especially valuable for those who seek to understand and apply mathematical concepts in real life. The book focuses on geometric inequalities and optimization problems, which is an important topic in mathematics. The authors share with readers many examples and tasks that will help develop analytical thinking and problem-solving skills. Each section of the book is permeated with the spirit of research work, which makes it not only a textbook, but also a source of inspiration for future mathematicians and scientists. For whom is this book intended? First of all, it will be of interest to students of mathematical and engineering specialties, as well as teachers who are looking for quality materials for their courses . However, a wider audience, including high school students and math lovers, will find much useful in it. The book is suitable for those who want to deepen their knowledge in the field of geometry and learn how to apply them in various tasks, from simple to complex. The topics raised in the book cover a wide range of issues, from basic geometric concepts to complex inequalities, such as the Koi-Bunjakovsky inequalities and others. The authors not only explain the theory, but also demonstrate how these ideas can be used to solve practical problems. This makes the book especially valuable for those who want not only to study mathematics, but also to apply it in real situations, whether in science, technology or everyday life. The style of the authors is clear and accessible, which allows readers to easily assimilate even the most complex concepts. D. About. Shklyarsky, N. N. Chentsov and I. M. Yaglom are well-known mathematicians, each of whom has considerable experience in teaching and scientific activities. Their previous works, such as Mathematical Analysis and Elements of Mathematical Analysis, have already established themselves as qualitative and useful sources of knowledge. In this book, they continue their tradition, offering readers not only theory but also practical skills that can be applied in various fields. Do not forget that "Geometric inequalities and tasks to a maximum and minimum" is not just a textbook, but a real guide to the world of mathematics. By reading it, you will be able not only to understand complex issues, but also to develop your analytical abilities, which will be useful in any field of activity. The book encourages reflection and the search for non-standard solutions, which makes it an excellent tool for the development of creative thinking. Thus, if you are looking for a high-quality and deep edition of geometry that will help you not only understand, but also love mathematics, “Geometric inequalities and tasks to a maximum and minimum” will be an excellent choice for you. Immerse yourself in the world of numbers, forms and inequalities, and discover new horizons of knowledge along with this wonderful book!
