Let $p>3$ be prime, let $l\equiv p-1\pmod p$ be prime, and let $E_p$ be the Tate normal form for a point of order $p$. Write $\hat H_{p,l}(x)$ for its Hasse invariant over…

Let $l\neq 2,3,7$ be a prime. Let $\hat H_{7,l}(x)$ denote the Hasse invariant polynomial of the Tate normal form $E_7$ over $\mathbb F_l$, and let $h(-l)$ denote the relevant clas…
