On Enriques-Babbage Theorem for singular curves
Lia Feital, Naamã Galdino, Renato Vidal Martins +1
We propose a version of the Enriques-Babagge Theorem for a singular curve , involving its canonical model . We provide a partial proof for an arbitrary curve and complet…
On Clifford dimension for singular curves
Lia Feital, Naamã Galdino, Renato Vidal Martins +1
We study the Clifford dimension of an integral curve. To do so, we extend the notion of Clifford index, allowing torsion-free sheaves on its computation. We derive results for arbi…
Singular rational curves with points of nearly-maximal weight
Ethan Cotterill, Lia Feital, Renato Vidal Martins
In this article we study rational curves with a unique unibranch genus- singularity, which is of {\it $\ka$-hyperelliptic} type in the sense of \cite{To}; we focus on the cases…
Dimension counts for singular rational curves via semigroups
Ethan Cotterill, Lia Feital, Renato Vidal Martins
We study singular rational curves in projective space, deducing conditions on their parametrizations from the value semigroups $\sss$ of their singularities. In particular, we prov…
