چکیده

In this paper the family of elliptic curves over Q given by the equation Ep :
Y² = (X - p)³ + X³ + (X + p)³ where p is a prime number, is studied. It
is shown that the maximal rank of the elliptic curves is at most 3 and some
conditions under which we have rank(Ep(Q)) = 0 or rank(Ep(Q)) = 1 or
rank(Ep(Q))≥2 are given.
