Galois subspaces for projective varieties
Robert Auffarth
Given an embedding of a projective variety into projective space, we study the structure of the space of all linear projections that, when composed with the embedding, give a Galoi…
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…
Theta divisors whose Gauss map has a fiber of positive dimension
Robert Auffarth, Giulio Codogni
We construct families of principally polarized abelian varieties whose theta divisor is irreducible and contains an abelian subvariety. These families are used to construct example…
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…
