Guide to the Classification Theorem for Compact Surfaces

From the reviews: "The book would make an excellent graduate or advanced undergraduate project. ... audience would be instructors or researchers looking to reconnect to some topology fundamentals. Practitioners in topology-adjacent fields might find it valuable as a concise reference. ... a textbook or supplemental reference for a second topology course with some careful planning ... . Academic libraries should strongly consider this book as it offers a broad look at material common to a standard undergraduate mathematics curriculum." (Bill Wood, MAA Reviews, March, 2014) "This book aims to give students ... access to a true classic in algebraic topology: the classification of compact surfaces (up to homeomorphism). ... The book includes many historical comments throughout and contains lots of pictures----both of the mathematicians involved in the classification theorem and of examples illustrating the mathematical content. Many examples are given that help one understand the basic tools ... ." (Clara L h, Mathematical Reviews, December, 2013) "This highly focused book by Gallier (Univ. of Pennsylvania) and Xu (Bryn Mawr College) does both, delivering rigor to undergraduates by developing minimal doses of homotopy and homology theory, and without even presuming familiarity with group theory. ... The present careful treatment of a major result that draws from several branches of mathematics makes the book an excellent resource for a capstone course. Summing Up: Highly recommended. Upper-division undergraduates and above." (D. V. Feldman, Choice, Vol. 51 (1), September, 2013) "The book is geared toward an audience including first-year graduate students but also strongly motivated upper-level undergraduates ... . the book under review offers a beautiful introduction to one of the oldest and most fascinating theorems in algebraic topology ... . the historical remarks concerning the classification theorem for compact surfaces are highly enlightening to anyone interested in topology, and the many related biographies and photographs are just as entertaining. ... No doubt, this is an introductory text of remarkable didactic value." (Werner Kleinert, zbMATH, Vol. 1270, 2013)
