Abstract.
We construct infinitely many Shimura curves (1-dimensional special subvarieties, which are in particularly totally geodesic) of the moduli space of abelian varieties, contained in the locus of hyperelliptic Jacobians in genus 3, and in the locus of Jacobians in genus 4 - only finitely many such examples were previously known. Joint work with Martin Moeller.
