Decomposition and endomorphism algebra

All geometric endomorphisms are defined over $\F_{53}$.

Endomorphism algebra over $\F_{53}$

The isogeny class factors as 1.53.ak $\times$ 1.53.f and its endomorphism algebra is a direct product of the endomorphism algebras for each isotypic factor. The endomorphism algebra for each factor is:

• 1.53.ak : \(\Q(\sqrt{-7}) \).
• 1.53.f : \(\Q(\sqrt{-187}) \).
