Curves of Genus 2 with sqrt2 Multiplication, by Peter R. Bending
In this paper, we give a universal family of curves of genus $2$ whose
jacobians have $\sqrt2$ multiplication fixed by the Rosati involution,
and several results based on it, including isogenies between jacobians
of curves, and jacobians of curves with quaternionic multiplication.
