Characterization of some projective subschemes by locally free resolutions
Uwe Nagel
A locally free resolution of a subscheme is by definition an exact sequence consisting of locally free sheaves (except the ideal sheaf) which has uniqueness properties like a free…
Non-degenerate curves with maximal Hartshorne-Rao module
Uwe Nagel
Extending results for space curves we establish bounds for the cohomology of a non-degenerate curve in projective -space. As a consequence, for any given we determine all po…
The Weak and Strong Lefschetz Properties for Artinian K-Algebras
T. Harima, J. Migliore, U. Nagel +1
Let A = bigoplus_{i >= 0} A_i be a standard graded Artinian K-algebra, where char K = 0. Then A has the Weak Lefschetz property if there is an element ell of degree 1 such that the…
