Effective radical parametrization of trigonal curves
Josef Schicho, David Sevilla
Let be a non-hyperelliptic algebraic curve. It is known that its canonical image is the intersection of the quadrics that contain it, except when is trigonal (that is, it h…

Deciding trigonality of algebraic curves
Josef Schicho, David Sevilla
Let C be a non-hyperelliptic algebraic curve of genus at least 3. Enriques and Babbage proved that its canonical image is the intersection of the quadrics that contain it, except w…

Lattice polygons and families of curves on rational surfaces
Niels Lubbes, Josef Schicho
First we solve the problem of finding minimal degree families on toric surfaces by reducing it to lattice geometry. Then we describe how to find minimal degree families on, more ge…
