The origin of the Frey elliptic curve in a too narrow margin
arXiv:1604.03753
Abstract
It is shown that an appropriate use of so-called double equations by Diophantus provides the origin of the Frey elliptic curve and from it we can deduce an elementary proof of Fermat's Last Theorem.
The paper is incomplete and the statement of the Fundamental Theorem is inadequate. Therefore, the paper is obsolete
