Lower bounds on expressions depending on the functions {\boldmath$\ddot{I}†(n)$}, {\boldmath$\ddot{I}ˆ(n)$} and {\boldmath$\ddot{I}ƒ(n)$}, III

Abstract

This work is concerned with the study of lower bounds for various expressions related to the arithmetic functions $\ddot{I}†(n)$, $\ddot{I}ˆ(n)$ and $\ddot{I}ƒ(n)$. Several explicit estimates are established.
