Logarithmic bundles and line arrangements, an approach via the standard construction
Résumé
We propose an approach to study logarithmic sheaves T P n (− log DA) associated with hyperplane arrangements A on the projective space P n , based on projective duality, direct image functors and vector bundles methods. We focus on free line arrangements admitting a point with high multiplicity, or having low exponents, proving Terao's conjecture in this range.
