ACCURATE COMPUTATIONS OF EULER PRODUCTS OVER PRIMES IN ARITHMETIC PROGRESSIONS

摘要

This note provides accurate truncated formulae with explicit error terms to compute Euler products over primes in arithmetic progressions of rational fractions. It further provides such a formula for the product of terms of the shape F(1=p; 1=p~s) when F is a two-variable polynomial with coefficients in C and satisfying some restrictive conditions.
