A further criterion can be formulated by the formal group G associated to E. Since K is of positive characteristic, we can define its height ht (G), which is 2 if and only if E is supersingular and else is 1.
Since "K" is of positive characteristic, we can define its height ht ("G"), which is 2 if and only if E is supersingular and else is 1. A further criterion can be formulated by the formal group "G" associated to "E".
