ABSTRACT

Let $p>3$ be a prime, and let $m$ be an integer with $p\nmid m$. In the
paper, by using the work of Ishii and Deuring's theorem for elliptic curves
with complex multiplication we solve some conjectures of Zhi-Wei Sun concerning
$\sum_{k=0}^{p-1}\binom{2k}k^2\binom{4k}{2k}m^{-k}\mod {p^2}$.
