Fermat's Theorem – Fermat's Own Proof

[Greg71]

Dear colleagues,

From 1990 to 2025, I worked on restoring Fermat's original proof of his theorem. There was a 23-year break in my work from 1993 to 2016, but in the end, I believe I have succeeded.

But did I really succeed? Please take a look!

Yes I have downloaded this pdf as the subject is interesting.

However I wonder how you consider it restores Fermat's original proof ?

You have quite a few pages of algebra and calculus to wade through, though they may indeed be correct I can't reconcile them with the simplicity Fermat claimed, not the algebra and other mathematics of his time.
