| Oct 8, 2019 at 3:57 | comment | added | Zhiyu | @reuns Two elliptic curves over a finite field $\mathbb F_q$ are isogenus iff they have same number of $\mathbb F_q$ points, which is determined by the Frobenius action. This is quite standard, and is not the key point. | |

| Oct 8, 2019 at 3:46 | comment | added | Zhiyu | @reuns Here we work over an algebraically closed field $k$, and you can choose a specific descent to $\mathbb F_{p^2}$ then the result is standard, for example see mathoverflow.net/questions/18982/…. | |
