## Fermat's last theorem and undecidability - useful books

This page lists books related to the article Is Fermat's last theorem undecidable? |

### General Books - Fermat's Last Theorem

*Fermat's Last Theorem: The Story of a Riddle That Confounded the World's Greatest Minds for 358 Years*by

**Simon Singh**combines a history of the mathematics leading up to the proof with a biographical description of Wiles' work - how he decided he was going to prove it when he was 10 years old, and succeeded 30 years later. Note that this book is essentially the same as the earlier

*Fermat's Enigma : The Epic Quest to Solve the World's Greatest Mathematical Problem*

Alternatively there's * Fermat's Last Theorem : Unlocking the Secret of an Ancient Mathematical Problem* by

**AMIR D. ACZEL**this is shorter (160 pages compared with 362 for Singh's book), but covers a wider area of the history of mathematics, and so is less detailed. It also has more on the history of Modular Forms.

You may also be interested in the books by **Charles J. Mozzochi**. *The Fermat Diary*, gives a description of Wiles' work on the proof, and * The Fermat Proof* which is a very short book (only 50 pages in total) gives an outline of the mathematics used in the proof.

### General Books - Undecidability

If you want to know about undecidability in mathematics, there are a couple of books, both of which deal with the philosophical developments in a readable way, although they both could also be described as being about the history of mathematics. In fact *Pi in the Sky* by **John Barrow** is really two different books in one, the first part being a history of counting, the second a description of the ideas in mathematical logic which arose around the ideas of Cantor and Godel. Unfortunately Barrow is a believer in 'real' undecidability, which I have argued against, but if you overlook that the book is well worth reading. The other book is *Mathematics, The loss of certainty* by **Morris Kline**, who puts forward the view that mathematics has an image of certainty, but in truth has never deserved this. The trouble is he seems to claim much more than the evidence supports, and I found the early part of the book rather off-putting. However it does improve in the later chapters.

### More advanced books - Fermat's last theorem

I've heard that to understand Wiles' proof of Fermat's Last Theorem would take ten years of continuous study from the level of undergraduate mathematics. I'm not sure I believe it, so don't let it discourage you. If you're looking for an informal description of the route to the proof then you might like*Notes on Fermat's Last Theorem*by

**Alfred van der Poorten**. However be warned - informal here means 'in the style of mathematicians talking to each other', so you need fairly advanced mathematics as a prerequisite and you also need to be happy with this 'informal' style.

Possibly more suited to the mathematics student wanting to understand some of the proof is *Algebraic number theory and Fermat's last theorem* by **Ian Stewart** and **David Tall**. As the title suggests this is mostly about Algebraic number theory, but it does include some material on modular forms and elliptic curves, which are a crucial part of the proof. For myself, I'm working my way through *Invitation to the Mathematics of Fermat-Wiles* by **Yves Hellegouarch**, which seems to me to be the best choice for getting a real grasp of the proof.

### More advanced books - undecidability

This is part of the subject of mathematical logic, and books on this can be somewhat obscure - it's worth checking to find ones which are reasonably readable. Two such books are*A mathematical introduction to logic*by

**H.B. Enderton**and

*A friendly introduction to mathematical logic*by

**Christopher Leary**. For a comprehensive coverage of the subject there is

*Handbook of Mathematical logic*by

**Jon Barwise**, which has over 1000 pages, and would be useful as a reference work. If you are specifically interested in Non-standard models of the integers then you should consider

*Models of Peano Arithmetic*by

**Richard Kaye**, which contains advanced mathematics, but is well laid out for study.
