On the singularities of surfaces ruled by conics

Michela Brundu, Gianni Sacchiero

We classify the singularities of a surface ruled by conics: they are rational double points of type $A_{n}$ or $D_{n}$ . This is proved by showing that they arise from a precise series…

Stratification of the moduli space of four--gonal curves

Michela Brundu, Gianni Sacchiero

Let $X$ be a smooth irreducible projective curve of genus $g$ and gonality 4. We show that the canonical model of $X$ is contained in a uniquely defined surface, ruled by conics, w…
