Abstract
We compute the Mordell-Weil groups of the modular Jacobian varieties of hyperelliptic modular curves over every number field which is the composition of quadratic fields. Also we prove criteria for the existence of elliptic curves over such number fields with prescribed torsion points generalizing the results for quadratic number fields of Kamienny and Najman.
