Another theorem named after this man used the modularity conjecture, also called the Taniyama-Shimura Conjecture.
The Lucas primality test is based on one finding of this man who pioneered the method of infinite descent. That result is a specific case of a theorem that takes an element to the totient function of n-1, Euler's theorem. Numbers for which the converse of that theorem do not hold are called Carmichael Numbers. Another theorem named after this man used the modularity conjecture, also called the Taniyama-Shimura Conjecture. That theorem stating that for n greater than one there are no solutions to a to the n plus b to the n equals to c to the n for positive a, b, and c was proved by Andrew Wiles. For 10 points, identify this man with namesake "little" and "last" theorems.
