Pseudoreflections on Prym Varieties
Robert Auffarth, Martà Lahoz, Juan Carlos Naranjo
We show that for every g greater or equal than 5, the locus of Prym varieties in the moduli space of principally polarized abelian varieties of dimension g-1 that possess a pseudor…
On the Picard number and the extension degree of period matrices of complex tori
Robert Auffarth, Jorge Duque Franco
The rank of the Néron-Severi group of a complex torus of dimension satisfies The degree of the extension field generated ove…
A note on multisecants of the Kummer variety of a Jacobian
Robert Auffarth, Sebastián Rahausen
We show that if is a smooth projective curve and is a on , then we obtain a rational map $\mathrm{Sym}^{n}(C)\dashrightarrow\mathfrak{…
Counting polarizations on abelian varieties with group action
Robert Auffarth, Angel Carocca, Rubà E. RodrÃguez
Let be the moduli space of principally polarized abelian varieties. We study the problem of counting the number of principal polarizations modulo the natural action…
