## Outer Circles: An Introduction to Hyperbolic 3-Manifolds (Google eBook)We live in a three-dimensional space; what sort of space is it? Can we build it from simple geometric objects? The answers to such questions have been found in the last 30 years, and Outer Circles describes the basic mathematics needed for those answers as well as making clear the grand design of the subject of hyperbolic manifolds as a whole. The purpose of Outer Circles is to provide an account of the contemporary theory, accessible to those with minimal formal background in topology, hyperbolic geometry, and complex analysis. The text explains what is needed, and provides the expertise to use the primary tools to arrive at a thorough understanding of the big picture. This picture is further filled out by numerous exercises and expositions at the ends of the chapters and is complemented by a profusion of high quality illustrations. There is an extensive bibliography for further study. |

#### Review: Outer Circles: An Introduction to Hyperbolic 3-Manifolds

User Review - Steve Dalton - GoodreadsThis book is full of facts about hyperbolic 3 manifolds with absolutely no connecting thread between these facts. There is virtually no motivation, big picture, "here's where we are going" in almost ... Read full review
