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{…

The Generalized Torelli Problem through the geometry of the Gauss map
Sebastián Rahausen
Given a non-hyperelliptic curve and , we prove that the generic fiber of the Gauss map on has one element and we characterize its multipl…

Galois subspaces for smooth projective curves
Robert Auffarth, Sebastián Rahausen
Given an embedding of a smooth projective curve of genus into , we study the locus of linear subspaces of of codimension 2 such that proje…

Galois subspaces for the rational normal curve
Robert Auffarth, Sebastián Rahausen
We characterize all -dimensional linear subspaces of such that the induced linear projection, when restricted to the rational normal curve, gives a Galois m…
