arXiv:1208.0926
Abstract
An overview of some basic notions is given, especially with an eye towards somewhat "fractal" examples, such as infinite products of cyclic groups, p-adic numbers, and solenoids.
184 pages, including a two-page index that can be obtained using "makeindex". Some material has been added to Chapter 3, and to a new Chapter 10. A few smaller additions and other changes have also been made
