François Proth
(重定向自Proth)
François Proth (1852 – 1879) was a French self-taught mathematician farmer who lived in Vaux-devant-Damloup near Verdun, France.
He stated four primality-related theorems. The most famous of these, Proth's theorem, can be used to test whether a Proth number (a number of the form k2 + 1 with k odd and k < 2) is prime. The numbers passing this test are called Proth primes; they continue to be of importance in the computational search for large prime numbers.
