An isogeny \(\varphi: E_1\to E_2\) between two elliptic curves \(E_1\) and \(E_2\) is a morphism of curves that sends the origin of \(E_1\) to the origin of \(E_2\).Such a morphism is automatically a morphism of group schemes and the kernel is a finite subgroup scheme of \(E_1\).Such a subscheme can either be given by a list of …
