The fibres of the Prym map of étale cyclic coverings of degree 7
Herbert Lange, Angela Ortega
We study the Prym varieties arising from étale cyclic coverings of degree 7 over a curve of genus 2. These Prym varieties are products of Jacobians JY x JY of genus 3 curves Y with…

Prym varieties of étale covers of hyperelliptic curves
Herbert Lange, Angela Ortega
It is well known that the Prym variety of an étale cyclic covering of a hyperelliptic curve is isogenous to the product of two Jacobians. Moreover, if the degree of the covering is…
