Guy Terjanian

French mathematician

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}} , then 2p must divide x or y.[3]
