Involutions on hyperelliptic curves and Prym maps

Algebraic Geometry 2024-10-31 v2

Abstract

We investigate the geometry of smooth hyperelliptic curves that possess additional involutions, especially from the point of view of the Prym theory. Our main result is the injectivity of the Prym map for hyperelliptic Z22\mathbb{Z}_2^2-coverings over hyperelliptic curves of positive genus.
