Components of the Hilbert scheme of space curves on low-degree smooth surfaces

Jan O. Kleppe, John C. Ottem

We study maximal families W of the Hilbert scheme, H(d,g)_{sc}, of smooth connected space curves whose general curve C lies on a smooth surface S of degree s. We give conditions on…

Partially ample line bundles on toric varieties

Nathan Broomhead, John Christian Ottem, Artie Prendergast-Smith

In this note we study properties of partially ample line bundles on simplicial projective toric varieties. We prove that the cone of q-ample line bundles is a union of rational pol…
