Найти книгу: "A Course on Group Theory"

This textbook for advanced courses in group theory focuses on finite groups, with emphasis on the idea of group actions. Early chapters summarize presupposed facts, identify important themes, and establish the notation used throughout the book. Subsequent chapters explore the normal and arithmetical structures of groups as well as applications. Topics include the normal structure of groups: subgroups; homomorphisms and quotients; series; direct products and the structure of finitely generated Abelian groups; and group action on groups. Additional subjects range from the arithmetical structure of groups to classical notions of transfer and splitting by means of group action arguments. More than 675 exercises, many accompanied by hints, illustrate and extend the material.

During the last decade, the martial arts world has looked to innovative mixed martial arts competitions such as the Ultimate Fighting Championship to determine which fighting style is the best. These contests have repeatedly shown the grappling style of martial arts, headed by Brazilian jiu-jitsu, to dominate. The Brazilian jiu-jitsu style stems from the premise, garnered from analysis of actual street fights, that the outcome of any fight is decided on the ground. While most martial arts deal only with the initial punching and kicking stages of combat, Brazilian jiu-jitsu concentrates on ground combat. This guide shows how to use Brazilian jiu-jitsu to increase combat effectiveness. Photographs and step-by-step instructions show how to master the techniques used in this exciting new form of combat. Renzo Gracie, a two-time world Abu Dhabi submission jiu-jitsu champion, two-time Brazilian national champion, World Combat champion, and Martial Arts Reality Superfight champion, teaches Brazilian jiu-jitsu at an elite martial arts academy. Royler Gracie has competed in the Black Belt ranks for 20 years, winning the world title four times and the Abu Dhabi world submission championship for two consecutive years. They live in New York City.
