On the Distribution of Pseudopowers

Number Theory 2019-08-15 v1

Abstract

An xx-pseudopower to base gg is a positive integer which is not a power of gg yet is so modulo pp for all primes pxp\le x. We improve an upper bound for the least such number due to E. Bach, R. Lukes, J. Shallit, and H. C. Williams. The method is based on a combination of some bounds of exponential sums with new results about the average behaviour of the multiplicative order of gg modulo prime numbers.
