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…

Hilbert Schemes and Toric Degenerations for Low Degree Fano Threefolds
Jan Arthur Christophersen, Nathan Owen Ilten
For fixed degree , we study the Hilbert scheme of degree smooth Fano threefolds in their anticanonical embeddings. We use this to classify all possible degenerations…
