Proceedings of the Group Theory Seminar, edited by Schmidt O. Yu. It is a unique collection that immerses the reader in the fascinating and complex world of mathematics, namely, in group theory. This edition will be especially interesting for those who seek to understand the structure and properties of mathematical objects, as well as for those who want to expand their knowledge in the field of algebra and abstract mathematics. Group theory is one of the fundamental branches of mathematics that studies the symmetries and structures that can be observed in various mathematical and physical systems. Schmidt and his colleagues’ book covers a wide range of topics, ranging from basic concepts to more complex concepts such as Lee groups and their applications. This makes the collection both a useful teaching aid for students and a valuable resource for researchers and educators working in the field. In the "Works of the Seminar" the authors share the results of their research, discuss new methods and approaches, and present interesting examples that will help the reader to better assimilate the material. Each chapter of the book is written taking into account the current issues and problems facing modern mathematicians, which makes it not only a theoretical, but also a practical guide. In this context, the book will be particularly useful for graduate students and young scientists who are looking for inspiration for their own research. The style of the author and editors is clear and accessible, which allows the reader to easily follow the course of thought and assimilate even the most complex concepts. Schmidt O. Yu. — a well-known mathematician and teacher who has already established himself in the scientific community thanks to his work in the field of algebra and group theory His other well-known works are also devoted to mathematical topics, and they often become desk books for students and faculty.[citation needed] The book raises many important topics, such as the relationship of group theory to other areas of mathematics, the role of symmetry in nature and art, and the application of group structures to physics and computer science. These aspects make the "Works of the seminar on group theory" not just a textbook, but a real bridge between various scientific disciplines. Readers interested in mathematics, physics, computer science and even philosophy will find in this book a lot of useful information and new ideas. If you are a student, graduate student or just a math enthusiast who wants to deepen your knowledge and understand how groups and symmetries work, this book will be a real find for you. It will not only expand your horizons, but also help you look at familiar things from a new perspective. Due to its content and style of presentation, "Works of the seminar on group theory" can be an important step on your way to understanding complex mathematical concepts. Thus, if you are looking for quality literature on group theory that combines deep theoretical knowledge and practical examples, do not miss the opportunity to get acquainted with this collection. It will become your reliable companion in the world of abstract mathematics and will open new horizons in the study of group theory.
