Jacobians and polarizations

This isogeny class is principally polarizable, but does not contain a Jacobian.

Decomposition and endomorphism algebra

All geometric endomorphisms are defined over $\F_{11}$.

Endomorphism algebra over $\F_{11}$

The isogeny class factors as 1.11.af^2 $\times$ 1.11.ae and its endomorphism algebra is a direct product of the endomorphism algebras for each isotypic factor. The endomorphism algebra for each factor is:

• 1.11.af^2 : $\mathrm{M}_{2}($\(\Q(\sqrt{-19}) \)$)$
• 1.11.ae : \(\Q(\sqrt{-7}) \).

Base change

This is a primitive isogeny class.
