Abstract: |
In this paper we find some lower and upper bounds of the form for the function , in which . Then, we consider as generalization of , such that and is Euler constant; this extension has been introduced for the first time by J. Sándor and it helps us to find some lower and upper bounds of the form for the function and using these bounds, we show that , when is equivalent with the Prime Number Theorem.
