Shimura subvarieties via endomorphisms
Shimura subvarieties via endomorphisms
We prove that there exist two families in ℳ 2 ,ℳ 3 of non-Galois covers of the projective line whose Jacobians trace out Shimura subvarieties of 𝒜 2 ,𝒜 3 . They provide the first two explicit examples of Shimura subvarieties obtained by means of Jacobians carrying non-trivial endomorphisms not …
