On the constants in Mertens' theorems for primes in arithmetic progressions
arXiv:2306.09981
Abstract
A 1976 result from Norton may be used to give an asymptotic (but not explicit) description of the constant in Mertens' second theorem for primes in arithmetic progressions. Assuming the Generalized Riemann Hypothesis, we give an effective description of Norton's observation.
