Decomposition of Jacobians by Prym varieties / Herbert Lange, Rubí E. Rodríguez.
This monograph studies decompositions of the Jacobian of a smooth projective curve, induced by the action of a finite group, into a product of abelian subvarieties. The authors give a general theorem on how to decompose the Jacobian which works in many cases and apply it for several groups, as for g...
