The zsigmondy theorem
WebFor any $k\geq 1$, there are infinitely many solutions of the congruence $2^{n+k}\equiv 1\pmod{n}$. To see this, observe first that there is always a solution $ http://yamashita-lab.net/hp_math_ref/zsigmondy_theorem_by_thompson.pdf

WebWe present simple proofs of Walter Feit’s results on large Zsigmondy primes. We present simple proofs of known results related to Zsigmondy primes. We recall that if a, n are integers greater than 1, then a prime p is called a Zsigmondy prime for 〈a, n〉 if p a and the order of a (mod p) equals n (see [2], [4, §5], and Theorem 3 below). If p is a Zsigmondy … Web9 Aug 2024 · By Zsigmondy's Theorem, there exists a prime divisor p of a 2 n − b 2 n which does not divide a k − b k for all k < 2 n unless: n = 1 and a + b is a power of 2 n = 3, a = 2, b = 1 In particular, p does not divide a 2 k − b 2 k = ( a k − b k) ( a k + b k) for k < n . It remains to check the case n = 1 and a + b a power of 2 .

Web{Silverman proved the analogue of Zsigmondy's Theorem for elliptic divisibility sequences. For elliptic curves in global minimal form, it seems likely this result is true in a uniform manner. We present such a result for certain infinite families of curves and points. Our methods allow the first explicit examples of the elliptic Zsigmondy Theorem to be exhibited. incyte oral pd1WebThe classical Zsigmondy theorem (see [29]) is concerned with the sequence {An − Bn} n≥1,whereA and B are coprime positive integers. More precisely, the Zsigmondy set Z({An − Bn}n≥1) is a finite set. With the help of a deep result of Baker, this theorem was generalized by Schinzel [23] to any number field. Bilu incyte oncology productsWebBang-Zsigmondy’s theorem has many applications; for example, the existence of Zsigmondy primes was used in the original proof of Wedderburn’s theorem [20].
