The book "When any group of N elements is cyclical" by the authors Skopenkov A. , Bragina B. and the Glove A. is a fascinating and in-depth study in the field of abstract algebra, which will not leave indifferent any lover of mathematics This work is not just a textbook, but a real scientific monograph, in which the authors share their original views on the structure of groups and their properties. On the pages of the book, the reader will find a detailed analysis of the conditions under which a group of N elements can be recognized as cyclic. This concept, although it seems at first glance simple, opens up a whole world of interesting problems and theorems for researchers. The authors, possessing rich experience in the field of mathematics, offer readers not only theoretical calculations, but also practical examples that will help to better understand and assimilate the material. The book will be of interest to both students studying higher mathematics and teachers who want to deepen their knowledge in the field of algebra. It will also attract the attention of graduate students and researchers working in the field of group theory and algebraic structures. If you are passionate about mathematics, love to solve problems and strive for a deep understanding of abstract concepts, then this publication will be a real find for you. The topics raised in the book cover a wide range of issues related to groups, their subgroups, and isomorphisms. The authors consider in detail the various methods of proof, which allows the reader not only to follow the authors' thoughts, but also to develop their own skills of logical thinking. The book also touches on issues related to the application of group theory in other areas of mathematics and science, which emphasizes its interdisciplinary nature. The style of the authors is distinguished by clarity and accessibility, which makes complex mathematical concepts more understandable. Skopenkov, Bragin and Klyachko are well-known scientists whose work has already earned recognition in scientific circles. Their previous publications, such as Foundations of Group Theory and Algebraic Structures, have also been noted for their originality and depth of presentation, which confirms the high level of their scientific approach.
