Macaulay duality and its geometry

Steven L. Kleiman, Jan O. Kleppe

Macaulay Duality, between quotients of a polynomial ring over a field, annihilated by powers of the variables, and finitely generated submodules of the ring's graded dual, is gener…

The representation type of determinantal varieties

Jan O. Kleppe, Rosa M. Miró-Roig

This work is entirely devoted to construct huge families of indecomposable arithmetically Cohen-Macaulay (resp. Ulrich) sheaves E of arbitrary high rank on a general standard (resp…

The Hilbert scheme of space curves sitting on a smooth surface containing a line

Jan O. Kleppe

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

On the normal sheaf of determinantal varieties

Jan O. Kleppe, Rosa M. Miró-Roig

Let X be a standard determinantal scheme X \subset \PP^n of codimension c, i.e. a scheme defined by the maximal minors of a t \times (t+c-1) homogeneous polynomial matrix A. In thi…
