Since 2 and 6 hold for arbitrary
c-vectors,
it is clear that
(A) = (B) and that when y = B(x) one has...
...the Pythagorians knew infinitely many solutions in integers to
a2 + b2 = c2.
That no non-trivial integer solutions exist for
an + bn = cn with integers n > 2 has long
been suspected (Fermat, c.1637). Only during the current decade has this been proved (Wiles, 1995).
