On the Structure of the Weil Restriction of Abelian Varieties

Claus Diem, N. Naumann

We give a description of endomorphism rings of Weil restrictions of abelian varieties with respect to finite Galois extensions. The results are applied to study the isogeny decompo…

Families of elliptic curves with genus 2 covers of degree 2

Claus Diem

We study genus 2 covers of relative elliptic curves over an arbitrary base in which 2 is invertible. Particular emphasis lies on the case that the covering degree is 2. We show tha…
