Generic Curves of Small Genus in IP3 are of Maximal Rank.
Graded Betti numbers of some embedded rational n-folds.
Immersions of module varieties
We show that a homomorphism of algebras is a categorical epimorphism if and only if all induced morphisms of the associated module varieties are immersions. This enables us to classify all minimal singularities in the subvarieties of modules from homogeneous standard tubes.
Invariant Subvarieties of Toric Varieties Which are Local Complete Intersections.
Joacobian surfaces in P4.
Linear Systems on Projective Spaces.
Local embeddings of lines in singular hypersurfaces
Lines on hypersurfaces with isolated singularities are classified. New normal forms of simple singularities with respect to lines are obtained. Several invariants are introduced.
Logarithmic embeddings of varieties with normal crossings and mixed Hodge structures.
