动态序列的Prime Factors

Prime Factors of Dynamical Sequences

Xander Faber, Andrew Granville

摘要:

设f(t)是一个次数至少为2的有理系数的有理函数。对于给定的有理数x_0,对每个非负整数n定义x_{n+1} =f(x_n)。如果这个序列最终不是周期性的,那么差x_{n+1} -x_n对于所有足够大的n都有一个本原素因子。这一结果提供了一个新的证明,证明了对于任意次数至少为2的有理函数f,素数是无穷大的。

英文摘要:

Let f(t) be a rational function of degree at least 2 with rational coefficients. For a given rational number x_0, define x_{n+1}=f(x_n) for each nonnegative integer n. If this sequence is not eventually periodic, then the difference x_{n+1}-x_n has a primitive prime factor for all sufficiently large n. This result provides a new proof of the infinitude of primes for each rational function f of degree at least 2.
