$L$-FUNCTIONS OF ELLIPTIC CURVES AND BINARY RECURRENCES
Published online by Cambridge University Press: 22 March 2013
Abstract
Let $L(s, E)= {\mathop{\sum }\nolimits}_{n\geq 1} {a}_{n} {n}^{- s} $ be the
$L$-series corresponding to an elliptic curve
$E$ defined over
$ \mathbb{Q} $ and
$\mathbf{u} = \mathop{\{ {u}_{m} \} }\nolimits_{m\geq 0} $ be a nondegenerate binary recurrence sequence. We prove that if
${ \mathcal{M} }_{E} $ is the set of
$n$ such that
${a}_{n} \not = 0$ and
${ \mathcal{N} }_{E} $ is the subset of
$n\in { \mathcal{M} }_{E} $ such that
$\vert {a}_{n} \vert = \vert {u}_{m} \vert $ holds with some integer
$m\geq 0$, then
${ \mathcal{N} }_{E} $ is of density
$0$ as a subset of
${ \mathcal{M} }_{E} $.
