Is an abelian surface containing an elliptic curve a bielliptic surface?
Suppose I have an abelian surface $A$ over the complex numbers that contains an elliptic curve $E$. Then $A \to A/E$ is an elliptic fibration. The abelian surface $A$ will also contain a complementary elliptic curve $F$. Then $A \to A/F$ should also define an elliptic fibration.
Does this make A bielliptic? And does this always hold so long as it contains one elliptic curve?
