On the density of primes in arithmetic progression having a prescribed primitive root, by Pieter Moree
Let a,f and g be integers, with a and f coprime. Under the generalized
Riemann hypothesis it follows from work of Hooley and Lenstra that
the set of primes p such that p=a(mod f) and g is primitive root mod p
has a natural density. In this note we explicitly evaluate this density
and give some applications of this result.
