Continuing previous studies of the Beurling zeta function, here, we prove two results, generalizing long existing knowledge regarding the classical case of the Riemann zeta function and some of its generalizations. First, we address the question of Littlewood, who asked for explicit oscillation results provided a zeta-zero is known. We prove that given a zero rho(0) of the Beurling zeta function zeta(P) for a given number system generated by the primes P, the corresponding error term Delta(x) := psi(P)(x) - x, where psi(P)(x) is the von Mangoldt summatory function shows oscillation in any large enough interval, as large as pi/2-epsilon/vertical bar rho(0)vertical bar X-R rho 0. The somewhat mysterious appearance of the constant pi/2 is explained in the study. Finally, we prove as the next main result of the paper the following: given epsilon > 0, there exists a Beurling number system with primes P, such that vertical bar Delta (x)vertical bar <= pi/2+epsilon/vertical bar rho(0)vertical bar X-R rho 0. In this 2nd part, a nontrivial construction of a low norm sine polynomial is coupled by the application of the wonderful recent prime random approximation result of Broucke and Vindas, who sharpened the breakthrough probabilistic construction due to Diamond, Montgomery, and Vorhauer.
