Abelian varieties and Riemann surfaces with generalized quaternion group action

Angel Carocca, Sebastián Reyes-Carocca, Rubí E. Rodríguez

In this article we consider Riemann surfaces and abelian varieties endowed with a group of automorphisms isomorphic to a generalized quaternion group. We provide isogeny decomposit…

-étale covers of cyclic -gonal covers

Angel Carocca, Rubén Hidalgo, Rubí E. Rodríguez

In this paper we study the Galois group of the Galois cover of the composition of a -cyclic étale cover and a cyclic -gonal cover for any odd prime . Furthermore, we give…

Decomposable Jacobians

Angel Carocca, Herbert Lange, Rubí E. Rodríguez

In this paper we give examples of smooth projective curves whose Jacobians are isogenus to a product of an arbitrarily high number of Jacobians

Equations for abelian subvarieties

Angel Carocca, Herbert Lange, Rubí E. Rodríguez

Given a finite group and an abelian variety acted on by , to any subgroup of , we associate an abelian subvariety on which the associated Hecke algebra $\ma…

Etale double covers of cyclic p-gonal covers

Angel Carocca, Herbert Lange, Rubí Rodríguez

This paper computes the Galois group of the Galois cover of the composition of an étale double cover of a cyclic -gonal cover for any prime . Moreover a relation between some…

A generalisation of Kani-Rosen decomposition theorem for Jacobian varieties

Sebastián Reyes-Carocca, Rubí E. Rodríguez

In this short paper we generalise a theorem due to Kani and Rosen on decomposition of Jacobian varieties of Riemann surfaces with group action. This generalisation extends the set…
