### Synopses & Reviews

The theory of elliptic curves involves a pleasing blend of algebra,
geometry, analysis, and number theory. "Rational Points on Elliptic
Curves" streses this interplay as it develops the basic theory,
thereby providing an opportunity for advance undergraduates to
appreciate the unity of modern mathematics. At the same time, every
effort has been made to use only methods and results commonly included
in the undergraduate curriculum. This accessibility, the informal
writing style, and a wealth of exercises make "Rational Points on
Elliptic Curves" an ideal introduction for students at all levels who
are interested in learning about Diophantine equations and arithmetic
geometry.

#### Review

"The book can be warmly recommended to teachers, students, to beginners and experts or anyone who would like to learn the fundamentals of this nice part of number theory." EUROPEAN MATHEMATICAL SOCIETY NEWSLETTER

#### Review

From the reviews: "The authors' goal has been to write a textbook in a technically difficult field which is accessible to the average undergraduate mathematics major, and it seems that they have succeeded admirably..."--MATHEMATICAL REVIEWS "This is a very leisurely introduction to the theory of elliptic curves, concentrating on an algebraic and number-theoretic viewpoint. It is pitched at an undergraduate level and simplifies the work by proving the main theorems with additional hypotheses or by only proving special cases. ... The examples really pull together the material and make it clear. ... a great book for a first introduction to the subject of elliptic curves. ... very clearly written and you will understand a lot when you are done." (Allen Stenger, The Mathematical Association of America, August, 2008)

#### Synopsis

In 1961 the second author deliv1lred a series of lectures at Haverford Col lege on the subject of "Rational Points on Cubic Curves. " These lectures, intended for junior and senior mathematics majors, were recorded, tran scribed, and printed in mimeograph form. Since that time they have been widely distributed as photocopies of ever decreasing legibility, and por tions have appeared in various textbooks (Husemoller 1], Chahal 1]), but they have never appeared in their entirety. In view of the recent inter est in the theory of elliptic curves for subjects ranging from cryptogra phy (Lenstra 1], Koblitz 2]) to physics (Luck-Moussa-Waldschmidt 1]), as well as the tremendous purely mathematical activity in this area, it seems a propitious time to publish an expanded version of those original notes suitable for presentation to an advanced undergraduate audience. We have attempted to maintain much of the informality of the orig inal Haverford lectures. Our main goal in doing this has been to write a textbook in a technically difficult field which is "readable" by the average undergraduate mathematics major. We hope we have succeeded in this goal. The most obvious drawback to such an approach is that we have not been entirely rigorous in all of our proofs. In particular, much of the foundational material on elliptic curves presented in Chapter I is meant to explain and convince, rather than to rigorously prove."
