Abstract

In this paper, we study Landau’s inequality concerning primes counting function, asserting that $\pi(2x)<2\pi(x)$ for $x$  sufficiently large.  We give some variants of this inequality to study portion of primes in intervals with similar length.

Key Words: Landau’s inequality, prime numbers
