Abstract

In this talk, we discuss the density of subsets of natural numbers and an elementary estimate of primes. For example, we shall prove $$\underset{i\in\mathbb{P}\cap[n]}{\sum}\log{i}=O(n).$$

Here $\mathbb{P}$ and $[n]$ denote the set of all primes and all positive integers up to n respectively. Next, we shall show how to improve those results.
