Abstract
Any arrangement of hyperplanes in general position in $P^n$ can be regarded as a divisor with normal crossing. We study the bundles of logarithmic 1-forms corresponding to such divisors` from the point of view of classification of vector bundles on $P^n$. It turns out that all such bundles are stable. The study of jumping lines of these bundles gives a unified treatment of several classical constructions associating a curve to a collection of points in $P^n$. The main result of the paper is \"Torelli theorem\" which says that the collection of hyperplanes can be recovered from the isomorphism class of the corresponding logarithmic bundle unless the hyperplanes ocsulate a rational normal curve. In this latter case our construction reduces to that of secant bundles of Schwarzenberger.

The Projective Geometry of the Gale Transform

TL;DR: The Gale transform, an involution on sets of points in projective space, appears in a multitude of guises and in subjects as diverse as optimization, coding theory, theta functions, and recently in our proof that certain general sets of objects fail to satisfy the minimal free resolution conjecture as mentioned in this paper.

The module of logarithmic p-forms of a locally free arrangement

TL;DR: For an essential central hyperplane arrangement A ⊆ V ≃ k n+1, this article showed that 1 (A) gives rise to a locally free sheaf on P n if and only if for all X ∈ LA with rank X < dim V, the module 1 (AX) is free.

Chow quotients of Grassmannians. I

M. Kapranov
TL;DR: In this article, a certain compactification of the space of projective configurations is introduced by considering limit position (in the Chow variety) of the closures of generic orbits, which differs considerably from Mumford's geometric invariant theory quotient.
