Title: On the least primitive root of a prime p. (In English)

Review: Let g(p) denote the least positive primitive root for the prime p. Using an average of character sums, Hua proves that g(p) < 2m+1 p ½, where m is the number of prime divisors of p-1. Using Brun's method, Erdös proves that g(p) < p ½(log p)17, provided p is sufficiently large.
