Japanese mathematician

Taro Morishima (森嶋太郎, Morishima Tarō, 1903 – 1989) was a Japanese mathematician specializing in algebra who attended University of Tokyo in Japan. Morishima published at least thirteen papers, including his work on Fermat's Last Theorem.^[1] and a collected works volume published in 1990 after his death.^[2] He also corresponded several times with American mathematician H. S. Vandiver.^[3]

Morishima's Theorem on FLT

[edit ]

Let m be a prime number not exceeding 31. Let p be prime, and let x, y, z be integers such that x^p + y^p + z^p = 0. Assume that p does not divide the product xyz. Then, p2 must divide m^{p − 1}-1.

Review

[edit ]

Granville wrote that Morishima's proof could not be accepted. [1]
