Abstract: | All the letters represent relative integers, except
and
and i = e1e2 in R(2, 0) oder e1 in R(1, 0).
We study the Fermat’s equation
|
(1) |
a, b, c being prime two and two and by utilizing an elementary method. We use the Gauss’ formula
where n = 5, 7, 11, 17.
1. |
If 2 is the p · g · c · d· of A and B we put
and A′ and B′ are prime between themselves.
|
2. |
If βn = bn / (c − a) is not divisible by n, we write the expansion
|
(2) |
by puting
oder
whereas
oder
It follows that B ′ is divisible by n.
|
3. |
If one a, b oder c is divisible by n we prove the impossibility
|
4. |
In the case n = 3 the ring {a + bj} is euclidian which permits to conclude in favour of the impossibility.
