Genus three Ceresa cycles and limit of archimedean heights
Souvik Goswami, Irene Spelta
For a one-parameter variation of biextension mixed Hodge structures, Brosnan and Pearlstein showed that the limit of the asymptotic height of the variation is given by a certain li…
Families of cyclic curve coverings with maximal monodromy
Irene Spelta, Carolina Tamborini
We study the algebraic monodromy of families of cyclic Galois coverings of curves. Under a condition on the -decomposition of the associated variation of Hodge structures, we pr…
Monodromy of the Prym map and semicanonical pencils in genus 6
Martà Lahoz, Juan Carlos Naranjo, Andrés Rojas +1
The Prym map in genus 6 is dominant and generically finite of degree 27. When restricted to the divisor of curves with an odd semicanonical pencil …
Decomposable abelian -curves and special subvarieties
Irene Spelta, Carolina Tamborini
We consider families of abelian Galois coverings of the line. When the Jacobian of the general element is totally decomposable, i.e., is isogenous to a product of elliptic curves,…
Simplicity of some Jacobians with many automorphisms
J. C. Naranjo, A. Ortega, G. P. Pirola +1
We study an explicit -dimensional family of Jacobian varieties of dimension , arising from quotient curves of unramified cyclic coverings of prime degree…
