WebZsigmondy's theorem is often useful, especially in group theory, where it is used to prove that various groups have distinct orders except when they are known to be the same. History . The theorem was discovered by Zsigmondy working in Vienna from 1894 until 1925. http://yamashita-lab.net/hp_math_ref/zsigmondy_theorem_by_thompson.pdf

WebWeak Zsigmondy’s Theorem Batyrkhan Sakenov January 2024 Abstract Using the Zsigmondy’s theorem is not allowed on a large share of competitions of diverse levels, from the regional ones to the worldwide, such as IMO. The reason of this tendency lies in a highly complex proof of the theorem, which transcends the scope of the high school math. Web15 Nov 2024 · The classical Zsigmondy theorem [22] in 1892, extending earlier work of Bang [2] in the case b = 1, says that every term beyond the sixth in the sequence (a n − b n) n ≥ 1 has a primitive prime divisor, where a, b are positive coprime integers. This theorem was independently rediscovered by Birkhoff and Vandiver [4].

WebTheorem (Zsigmondy) For every pair of positive integers (a, n), except n = 1 and (2,6), there exists a prime p such that n = o (a mod p). Lets see why the exceptional cases might not work: If n = 1, then 1 = o (a mod p) a1 1 (mod p). But this is only true when a = 1.
