    Let \(K\) be a global field and \(E(K)\) be an elliptic curve defined over \(K\). For the points \(P\) of \(E(K)\) there are defined locally and globally the Weil height \(h(P)\), the modified Weil height \(d(P)\) and the Néron-Tate height \(\widehat{h}(P)\). In the present paper estimates for the differences \(\widehat{h}(P)-d(P)\), \(d(P)-h(P)\) and \(\widehat{h}(P)-h(P)\) are given. In the first part the curve is defined by a long Weierstrass equation \(y^2 + a_1 xy + a_3y = x^3 + a_2 x^2 + a_4x +a_6\), while in the second part by the special Weierstrass equation \(y^2 = x(x^2+cx+d)\). The estimates, which depend on the parameters of the Weierstrass equation, are too complicated to recapitulate here.NEWLINENEWLINEFor the entire collection see [Zbl 0976.00054].
