Abstract:

In this article we provide new explicit Chebyshev bounds for the prime counting function $\psi (x)$. The proof relies on two new arguments: smoothing the prime counting function which allows one to generalize the previous approaches, and a new explicit zero density estimate for the zeros of the Riemann zeta function.
