2010 Mathematics Subject Classification: Primary: 11D41 [MSN][ZBL]

The Diophantine equation $x^n+y^n=z^n$, $n\in \mathbb N$, $x,y\in \mathbb Z$, of which it was fairly recently proved (in 1995) that there are no non-trivial solutions if $n\geq3$ (see, e.g., [a1]).

See Fermat great theorem for an account of affairs before A. Wiles' recent proof [a3].

See Fermat last theorem and [a1] for a sketch of the basic ideas and techniques behind the proof. See also [a1] for related matters such as the generalized Fermat conjecture and the Fermat equation over function fields; see also [a2].
