Comparison theorems for deformation functors via invariant theory
Jan Arthur Christophersen, Jan O. Kleppe
We compare deformations of algebras to deformations of schemes in the setting of invariant theory. Our results generalize comparison theorems of Schlessinger and the second author…

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…
