Professors Gadea, Masqué and Mykytyuk have produced a workbook that appears to be an equally useful supplement for either a primarily theoretical or an application oriented course on differential geometry or differential topology.

This exceptional workbook puts me in mind of a mightily enhanced Schaum's outline, and I have an abiding respect for the educational value of the Schaum's series. A mastery of the material in this workbook would, I think, stand as compelling evidence of a very strong grounding in the fundamentals of modern differential geometry and related areas.

The authors deserve kudos for this admirable contribution to Springer's Problem Books in Mathematics series. It is bound to be an excellent learning tool for students of differential geometry and differential topology at any level as well as a handy reference for experts in these fields. In the gallery of scientific self-help literature, in which kitsch abounds, this workbook certainly qualifies as high art. One thing for sure, when next I teach a course in differential geometry or differential topology, I am certainly going to recommend this workbook as a supplementary text.

This is the second edition of a book which first appeared in 2001 under the name of the first two authors only. Its main intention is to provide a large collection of worked-out problems and exercises on modern differential geometry at an advanced undergraduate and graduate level. The prerequisites are some knowledge of linearand multilinear algebra, the calculus of several variables, point-set topology and some acquaintance with the concept of a manifold and the topology of fibre bundles.

The book contains 412 solved problems of varying degree of complexity and difficulty. They are spread over the first six chapters which deal with, respectively, the following topics: differentiable manifolds, tensor fields and differential forms, integration on manifolds, Lie groups, fibre bundles and Riemannian geometry. Each chapter starts with a brief overview of the main definitions, concepts and properties of the topic involved, and ends by making reference to some useful books for further reading. The material is presented in a clear and lucid way. With respect to the first edition, 39 problems have been deleted and 76 new problems have been added with, among others, some problems on symplectic geometry and Hamiltonian mechanics, on the adjoint representation of a Lie group, on homogeneous spaces related to the exceptional Lie group G_2, on the Godbillon-Vey class, and on the structure of the Kodaira-Thurston manifold. The final chapter, Chapter 7, provides an extended list of formulae from the calculus on manifolds, and tables concerning important spaces and Lie groups.

This book, which is rather unique in its kind, can be regarded as a valuable training book for everyone interested in becoming acquainted with the language and techniques of modern differential geometry. In particular, it can serve as a most helpful tool, both for students and teachers of a course on the subject. Moreover, the book is very nicely edited, containing many illustrative figures.

Second Edition

[Reviewed by Fernando Q. Gouvêa, on 02/13/2013]

The new edition has an added author and is published in hard covers. The authors tell us that 39problems have been deleted and 76 have been added. Other changes include: The Einstein summation convention is no longer used. (Hurray!) There is a section on what happens if one drops the standard topological assumptions (Hausdorff and second-countable) in the definition of a differentiable manifold. Several of the more advanced sections (on Lie groups, characteristic classes, connections) have been significantly expanded. A final chapter gives a collection of formulas and tables relevant to differential geometry. This book is an excellent resource for teachers and students of these topics.

First Edition

[Reviewed by Fernando Q. Gouvêa, on 04/13/2010]

This is a collection of solved problems on differentiable manifolds, Lie groups, and Riemannian geometry. It is intended as a supplement rather than as a standalone text. There are plenty of pictures to accompany the problems, including a few in color. The solutions are detailed, with many calculations written out in full, making some of the book's pages look like a mass of symbols.

The problems are complemented by two chapters, at the end of the book, intended to help orient the reader. The first is a kind of "fascicule de resultats": a collection of definitions and theorems. For most users of the book, the main role of this chapter will be to fix notation. Chapter 8, "Some Formulas and Tables," is more interesting. It collects such things as the general formula for stereographic projection, formulas for Lie derivatives and wedge products of differential forms, and lists of the classical groups and their Lie algebras. I find this chapter very useful, both in solving the problems in the book and as a place to find information quickly when Wikipedia is not reachable.

I suspect the book will be particularly useful to instructors who are not specialists in the subject; most of the results and problems here arelikely to be familiar to those working in the field. I would certainly want to have this book on hand if I were to teach such a course.
