Let $N$ be the level parameter, let $\alpha$ be the invariant, let $\operatorname{image}\alpha$ denote its image, let $\Phi_m^{\alpha}$ be the modular polynomial with level structu…

Let $N$ be the level parameter, let $\alpha$ be the invariant defining the modular polynomials with level structures, and let $J_1$ be the corresponding polynomial. For a polynomia…

Let $ell$ be a prime with $0<m<ell$, and let $a_{ell,ell-m}$ be the coefficient of the $ell$-th classical modular polynomial $\Phi_ell(X,Y)$. Suppose one of the following holds:…

Congruence conjecture. The following divisibilities hold: if $ell\ne 2$, then $a_{m,n}\equiv 0\pmod{2^{15c}}$; if $ell\ne 3$, then $a_{m,n}\equiv 0\pmod{3^{3c}}$, and if additional…
