This self-contained 2007 textbook presents an exposition of the well-known classical two-dimensional geometries, such as Euclidean, spherical, hyperbolic, and the locally Euclidean torus, and introduces the basic concepts of Euler numbers for topological triangulations, and Riemannian metrics. The careful discussion of these classical examples provides students with an introduction to the more general theory of curved spaces developed later in the book, as represented by embedded surfaces in Euclidean 3-space, and their generalization to abstract surfaces equipped with Riemannian metrics. Themes running throughout include those of geodesic curves, polygonal approximations to triangulations, Gaussian curvature, and the link to topology provided by the Gauss-Bonnet theorem. Numerous diagrams help bring the key points to life and helpful examples and exercises are included to aid understanding. Throughout the emphasis is placed on explicit proofs, making this text ideal for any student with a basic background in analysis and algebra.Read more
- A concrete approach to the theory, with emphasis on self-contained explicit proofs; uses the classical geometries to motivate the basic ideas of elementary differential geometry
- Provides a link between basic undergraduate courses on Analysis and Algebra, and more advanced theoretical courses in geometry
- Rigorous treatment of the classical geometries, via analytical ideas, with exercises at the end of each chapter, reinforcing the material in the text
- A novel approach to defining curvature on abstract surfaces, and to proving the topological invariance of the Euler number
- Coverage of a wide range of topics, starting with very elementary material and concluding with rather more advanced mathematical ideas
- Certain geometrical themes, such as geodesics, curvature, and the Gauss-Bonnet theorem, running throughout the book, provide a unifying philosophy

'… the patient reader will acquire substantial techniques and methods that are part of differential geometry and along with that, much, much more. … The book is certainly a welcome addition to the literature. It is clear to the reviewer the the text is a labour of love' Mathematical ReviewsSee more reviews
'This book paves its way through a number of geometries with a clear intent: to promote the understanding of the basic concepts in differential geometry. The classical 2-dimensional geometries such as Euclidean, spherical and hyperbolic geometry are the first few steps. The geometry of the torus, triangulations and Euler numbers are further issues. Every chapter is followed by an assortment of helpful examples. The chapters gently direct the reader [towards] Riemannian metrics and further to geodesics and abstract surfaces. The Theorema Egregium and Gauss-Bonnet Theorem are also given ample attention. What distinguishes this book from other lecture notes on elementary differential geometry? The author does not abruptly define concepts which otherwise never would have come to the reader's mind. He rather conveys the ideas, subtly initiated in the former chapters. In this sense the book is remarkably self-contained. On the other hand the author does not shun detailed proofs. All these ingredients make for a successful volume.' Johann Lang, Zentralblatt MATH
'Curved Spaces provides an elegant, sophisticated treatment of two-dimensional geometries suitable for advanced undergraduates … Overall, Wilson has provided a monograph that could ably serve for an excellent undergraduate capstone experience … Highly recommended.' S.J. Colley, CHOICE
'The book is written in a nice and precise style and explicit computations and proofs make the book easy to understand. A detailed and explicit discussion of the main examples of classical geometries contributes well to a better understanding of later generalisations. A list of examples at the end of each chapter helps as well. It is a very good addition to the literature on the topic and can be very useful for teachers preparing their courses as well as for students.' EMS Newsletter
