### Fermat's last theorem

Can anyone give me site with Fermat's last theorem proof by A. Whiles?

### Re: Fermat's last theorem

From http://cgd.best.vwh.net/home/flt/flt01.htm it seem that this site has the proof http://www.math.princeton.edu/~annals/i … 141_3.html but it seems that you can only get access to the article through certain universities.

### Re: Fermat's last theorem

Not my area either ... I think you would need a special interest in the subject to understand it. But interesting to read about, nonetheless

### Re: Fermat's last theorem

I have a great idea:
Do you want to understand it?
I'm offering to discute the proof from the begining to the end. We'll post what we don't understand.

Are you in?

### Re: Fermat's last theorem

2 (answer). As i understood it is just  Euclidean plane. Is that right?

### Re: Fermat's last theorem

3.(answer): I think I understood what is this.
But how to explain it?
A Riemann surface is a surface-like configuration that covers the complex plane with "sheets.". When we have a functin over the complex plaine C, which is not "single valued":
∃ z1,z2 ∈ C: (z1)=(z2)=y.
What will we get for the inverse function of (z)?

-¹(z) =={1-¹(z) OR 2-¹(z)}.
In the general case -¹(z) may be union of k "single valued" functions.
The riemann surface of -¹(z) is the union of the graphs of these functions.

We can use Euclidean plane, too.

### Re: Fermat's last theorem

Here's a simple example:
we use the function f(x)=x^2.(picture 1)
f-¹(y) = {sqrt(y) (picture 2) OR -sqrt(y) (picture 3)}
Then the Riemann surface of the function f-¹(y) is the union of the plots(picture 4)

### Re: Fermat's last theorem

I think the following site is the best:
I'm following the proof that siva(thank you) gave me.
There you can download the full solution. Or you can do this by clicking:
here for zipped .pdf file
here for PostScript
and here for .dvi
(I've tested only the .pdf format)

For example the function f=n!, defined over Natural numbers (N) has domain N. It also can be said "function f over N "
