Fermat's last theorem: when the integer n > 2, the equation x n+y n = z n about x, y and z has no positive integer solution.
Taylor formula: a function can be expressed by adding several terms, and these added terms are obtained by the derivative of the function at a certain point.
Lagrange theorem: it exists in many disciplines, namely: Lagrange mean value theorem in calculus; Sum theorem of four squares in number theory; Lagrange theorem in group theory? (group theory).
L'H?pital's Law: It is a method to determine the uncertainty under certain conditions by taking the derivative and limit of the numerator and denominator respectively. As we all know, the limit of the ratio of two infinitesimals or the ratio of two infinitesimals may or may not exist.
Brief introduction of Mahler Gobi theorem
Wolfskeil, a German, once announced that he would award 654.38 million marks to the first person who proved the theorem within 100 years after his death, which attracted many people to try and submit their "proofs".
After Fermat's last theorem was put forward, it experienced many people's conjectures and dialectics. After more than 300 years of history, finally in 1995, the British mathematician andrew wiles announced that he had proved Fermat's last theorem.
Fermat's last theorem and Riemann conjecture have become the carriers of M-theory geometric topology which combines general relativity and quantum mechanics.
