We define the notion of generalized logarithmic sheaves on a smooth projective surface,
associated to a pair consisting of a reduced curve and some fixed points on it. We then set …

Logarithmic Derivations of Adjoint Discriminants

We exhibit a relationship between projective duality and the sheaf of logarithmic vector fields
along a reduced divisor $ D $ of projective space, in that the push-forward of the ideal sheaf …
