The epsilon conjecture and Taniyama-Shimura conjecture were both useful in proving another theorem named for this man that stated there are no non-zero solutions to the equation a^n + b^n
Numbers that give a false result for a test named for this man satisfy the congruence b raised to the n minus one power similar to one mod one for all integers b that are relatively prime to n. Those numbers are a type of Knodel number named for Carmichael, also known as this man's pseudoprimes. The epsilon conjecture and Taniyama-Shimura conjecture were both useful in proving another theorem named for this man that stated there are no non-zero solutions to the equation a^n + b^n = c^n, when n is greater than two. For 10 points, name this French mathematician who is the namesake of a famous "last" theorem.
