Abstract
|
We give explicit uniform bounds for several quantities relevant
to the study of Galois representations attached to elliptic curves
.
We consider, in particular, the subgroup of scalars in the image of
Galois, the first Galois cohomology group with values in the torsion of
,
and the Kummer extensions generated by points of infinite order in
.
