Introduction Moduli uf algebraic curves and moduli of abelian varieties have completely ditferent aspects. Interplay between these two usually lead to difficult questions. From the complex analytic side, both moduli spaces are relatively well understood. The Schottky problem has been answered and that knowledge in some cases leads to intresting structure. Still many aspects are completely open. I want to study some of the related arithmetic questions. Statement of the problem Over the complex numbers. the classes of principally polarized abelian varieties (ppav) of dimension g>4, isogenous to jacobians are not the full moduli space of ppav: the proof uses strongly the fact that the field of complex numbers is uncountable and that isogenies of a ppav are countable. Over countable fields. the question is still open and I will try to find an answer. Ultimate goal I hope that this question and its solution lead to new insight in the interplay between these two moduli spaces, giving a better understanding of the Torelli locus. Eventually, I hope to answer arithmetic and geometric questions relating these two fascinating structure.
