    5 where `m` is a rational function giving the multiplication-by-`m` map.
     5where `m` is a rational function giving the multiplication-by-`m` map (the denominator of `m` is coprime to `psi`)

    77Instead of the above computation, the inverse direction is actually easier to compute: given `g`, we want to find `f` such that
