Guy Terjanian is a French mathematician who has worked on algebraic number theory. He achieved his Ph.D. under Claude Chevalley in 1970,[1] and at that time published a counterexample[2] to the original form of a conjecture of Emil Artin, which suitably modified had just been proved as the Ax-Kochen theorem.
In 1977, he proved that if p is an odd prime number, and the natural numbers x, y and z satisfy
x
2
p
+
y
2
p
=
z
2
p
{\displaystyle x^{2p}+y^{2p}=z^{2p}}
