WebSorted by: 39. An isogeny is a special kind of morphism between elliptic curves. An elliptic curve is, first of all, a curve; we want to be able to map from one curve to another. We already have a good notion of maps between curves, namely rational maps. But an elliptic curve is more than just a curve: it also has a distinguished point (the ... WebAbstract.
