Special Sets of Primes in Function Fields
Abstract
When investigating the distribution of the Euler totient function, one encounters sets of primes P where if p is in P then r is in P for all r|(p-1). While it is easy to construct finite sets of such primes, the only infinite set known is the set of all primes. We translate this problem into the function field setting and construct an infinite such set in Fp[x] whenever p is equivalent to 2 or 5 modulo 9.
