Buchsbaum-Rim sheaves and their multiple sections

J. C. Migliore, U. Nagel, C. Peterson

This paper begins by introducing and characterizing Buchsbaum-Rim sheaves on $Z = \Proj R$ where $R$ is a graded Gorenstein K-algebra. They are reflexive sheaves arising as the she…

Determinantal schemes and Buchsbaum-Rim sheaves

M. Kreuzer, J. C. Migliore, U. Nagel +1

Let $ϕ$ be a generically surjective morphism between direct sums of line bundles on $\proj{n}$ and assume that the degeneracy locus, $X$ , of $ϕ$ has the expected codimension. We ca…
