One inequality inspired by Erd\H{o}s

Number Theory 2025-03-06 v1

Abstract

Inspired by the proof of the Bertrand postulate given by P. Erd\H{o}S, we carefully examine and solve one less usual inequality in positive integers which could help to find an arithmetically pure proof that for every positive integer n2n\ge2 there is a prime pp such that n<p<2nn<p<2n.
