This book is concerned with analytic approaches of studying groups and their actions. Much attention is devoted to the study of amenability and Kazhdan's property (T), which are perhaps the most important analytic properties of a group, but we also discuss other analytic notions. We tried to introduce tricks, ideas and lemmas that repeatedly turn out to be useful in various situations. Our main guideline was to expose the beauty of the theory and to present many different aspects of it while keeping the text short, simple and accessible, sometimes at the expense of diving deep or providing thorough expositions. Hopefully this book could serve as a smooth entry to Analytic Group Theory. |
