E is
a fixed elliptic curve over the rational numbers.
Purpose:
To study the Néron-Tate
height of Heegner points on E.
Results:
We
get asymptotic formulae for
· the Néron-Tate
height of Heegner points on E on average over a
subset of discriminants: it is governed by the degree
of the modular parametrisation of E as geometry
suggests,
· the Néron-Tate
height of traces of Heegner points on average over a
subset of discriminants: we find a difference
according to the rank of the elliptic curve.
By Gross-Zagier formulae, it consists in proving asymptotic formulae
for the first moments of
· the derivative of the Rankin-Selberg convolution of E with a certain weight one theta
series attached to the principal ideal class of an imaginary quadratic field,
· the twisted L-function of E by a
quadratic Dirichlet character.
Many
experimental results are discussed.
Application:
These
results give some insight to the problem of the discretisation
of odd quadratic twists of elliptic curves.
