A Conjecture due to J. Oesterlé and D. W. Masser. It states that, for any Infinitesimal ,
there exists a Constant such that for any three Relatively Prime
Integers , , satisfying

the Inequality

holds, where indicates that the Product is over Primes which Divide the Product . If this Conjecture were true, it would imply Fermat's Last Theorem for sufficiently large Powers (Goldfeld 1996). This is related to the fact that the abc conjecture implies that there are at least Wieferich Primes for some constant (Silverman 1988, Vardi 1991).
