| Abstract: | We obtain an asymptotic formula for the number of square-free values among p−1, for primes p?x, and we apply it to derive the following asymptotic formula for L(x), the number of square-free values of the Carmichael function λ(n) for 1?n?x, |
| Keywords: | Square-free integers Carmichael function Wirsing theorem |
