Silverman, Joseph H.
Wieferich's criterion and the abc-conjecture.
(English)
[J] J. Number Theory 30, No.2, 226-237 (1988). ISSN 0022-314X; ISSN 1096-1658/e

The following result is proved. The so called ``abc-conjecture'' of Masser and Oesterlé implies that the number of primes less than X for which $\alpha\sp{p-1}\not\equiv 1 (mod p\quad 2)$ where $\alpha$ is a fixed rational number and $\alpha \ne \pm 1,0$, is at least O(log X). An analogous result is also proved for points of infinite order on elliptic curves having certain j-invariants. The proofs base on several skillfull lemmas.
