Restriction of the cotangent bundle to elliptic curves and Hilbert-Kunz fnctions
Holger Brenner, Georg Hein
We describe the possible restrictions of the cotangent bundle Ω_{\PP^N} to an elliptic curve C \subset \PP^N. We apply this in positive characteristic to the computation of the Hil…

Generalized Albanese morphisms
Georg Hein
We define generalizations of the Albanese variety for a projective variety X. The generalized Albanese morphisms X --> Alb_r(X) contract those curves C in X for which the induced m…

Residual intersection theory with reducible schemes
Georg Hein
We develop a formula (Theorem 5.1) which allows to compute top Chern classes of vector bundles on the vanishing locus of a section of this bundle. This formula particularly…
