On a sum involving the prime counting function $\pi(x)$

Number Theory 2007-05-23 v1

Abstract

A sharp asymptotic formula for the sum of reciprocals of π(n)\pi(n) is derived, where π(x)\pi(x) is the number of primes not exceeding xx. This result improves the previous results of De Koninck--Ivi\'c and L. Panaitopol.
