There we will also study analogous replacements for powers of ~ in the configuration space functional integral. integral changes but because H(p,q,T) changes. The new discretization is the prepoint discretization, since the resulting h depends on p,q and It T only. Therefore we obtain in fact immediately H(p,q,T).
