✦ Synopsis


Let a be an integer { &1 and not a square. Let P a (x) be the number of primes up to x for which a is a primitive root. Goldfeld and Stephens proved that the average value of P a (x) is about a constant multiple of xΓ‚ln x. Carmichael extended the definition of primitive roots to that of primitive *-roots for composite moduli n, which are integers with the maximal order modulo n. Let N a (x) be the number of natural numbers up to x for which a is a primitive *-root. In this paper we will prove that the average value of N a (x) oscillates. That is, lim x Γ„ 1Γ‚x 2 1 a x N a (x)>0 and x Γ„ 1Γ‚x 2 1 a x N a (x)=0.

Let P be a monic irreducible polynomial in F q [T ] such that d=deg P is even. We have obtained (B. AngleÁ s, 1999, J. Number Theory 79, 258 283), when q is odd, a class number congruence modulo P for the ideal class number of F q [T, -P] which is similar to the famous Ankeny Artin Chowla formula. A
