"The Kourov notebook: unsolved problems of group theory" is a unique edition, created under the editorship of the famous mathematician Mikhail Ilyich Kargapolov and his colleagues. The book is a collection of unsolved problems in the field of group theory, which is one of the most important branches of abstract algebra. This is not just a tutorial, but a real find for everyone who is interested in mathematics at a deep level. In this book you will find a variety of tasks that not only stimulate mental development, but also encourage the search for new solutions and approaches. Each task is provided with comments and explanations, which makes them understandable even to those who are not professional mathematicians. However, despite its accessibility, the tasks require a serious approach and in-depth analysis from the reader, which makes the book ideal for students, graduate students and teachers, as well as for anyone who is passionate about mathematics and wants to expand their knowledge. The book covers a wide range of topics related to group theory, including, but not limited to, the structure of groups, their representations and symmetries. These topics are relevant not only for pure mathematics, but also for applied fields such as physics, computer science, and even biology. Readers will be able to see how abstract mathematical concepts find their application in real-world problems, making the study of group theory particularly fascinating. The book will be of interest not only to students of mathematical specialties, but also to teachers who are looking for new approaches to learning. It can be an excellent addition to training courses and seminars, as well as a source of inspiration for scientific research.
