概要 We study the p-adic valuation of the values of normalised Hecke
eigenforms attached to non-isotrivial elliptic curves defined over
function fields of transcendence degree one over finite fields of
characteristic p. We derive upper bounds on the smallest attained
valuation in terms of the minimal discriminant under a certain
assumption on the function field and provide examples to show that
our estimates are optimal. As an application of our results we also
prove the analogue of the degree conjecture unconditionally for
strong Weil curves with square-free conductor defined over function
fields satisfying the assumption mentioned above.
