The average number of divisors of the Euler function

Sungjin Kim

The upper bound and the lower bound of average numbers of divisors of Euler Phi function and Carmichael Lambda function are obtained by Luca and Pomerance (see \cite{LP}). We impro…

On the Second Moment Estimate Involving the $λ$ -Primitive Roots Modulo $n$

Sungjin Kim

Artin's Conjecture on Primitive Roots states that a non-square nonunit integer $a$ is a primitive root modulo $p$ for the positive proportion of $p$ . This conjecture remains open,…
