Decomposition and endomorphism algebra
All geometric endomorphisms are defined over $\F_{59^{2}}$.
Endomorphism algebra over $\F_{59}$| The isogeny class factors as 1.59.ak $\times$ 1.59.k and its endomorphism algebra is a direct product of the endomorphism algebras for each isotypic factor. The endomorphism algebra for each factor is: |
| The base change of $A$ to $\F_{59^{2}}$ is 1.3481.s 2 and its endomorphism algebra is $\mathrm{M}_{2}($\(\Q(\sqrt{-34}) \)$)$ |
Base change
This is a primitive isogeny class.
