Abstract

In this paper the family of elliptic curves over Q given by the equation Ep : Y^{2} = (X - p)^{3} + X^{3} + (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.
