On the Picard number and the extension degree of period matrices of complex tori

Robert Auffarth, Jorge Duque Franco

The rank $ρ$ of the Néron-Severi group of a complex torus $X$ of dimension $g$ satisfies $0 \leq ρ \leq g^{2} = h^{1, 1} .$ The degree $d$ of the extension field generated over $…

A note on multisecants of the Kummer variety of a Jacobian

Robert Auffarth, Sebastián Rahausen

We show that if $C$ is a smooth projective curve and $d$ is a $g_{2 n}^{n}$ on $C$ , then we obtain a rational map $\mathrm{Sym}^{n}(C)\dashrightarrow\mathfrak{…
