The zsigmondy theorem

WebZsigmondy's Theorem was independently, but later, discovered by Birkhoff and Vandiver [2]. Of course it follows from Theorem A by checking that in cases (ii), (iii), and (iv) a Zsigmondy prime exists except when (a, m) - (2,6). Artin gave an elegant proof of the original result in [1]. The proof of Theorem A Web17 Mar 2024 · Zsigmondy’s theorem is a powerful result about the prime divisors of a^n-b^n an − bn, and can be used to solve a variety of math olympiad problems (see for instance this blog post by KingSmasher3 ).
