This theorem was originally called Fermat's last theorem, which was put forward by the French mathematician Fermat in the17th century. At that time, people called it "theorem", but they didn't believe that Fermat had proved it. Although Fermat claimed to have found a wonderful proof, it took three and a half centuries for andrew wiles, a British mathematician at Princeton University, and richard taylor, his student, to successfully prove this century's number theory in 1995. It is doubtful whether Fermat really found the correct proof because many new mathematics are used in the proof, including elliptic curves and modular forms in algebraic geometry, Galois theory and Heck algebra. Andrew wiles won the Fields Prize of 1998 and the Shaw Prize for Mathematics in 2005 because he successfully proved this theorem.
