We describe dualities and complexes of logarithmic forms and differentialsfor central affine and corresponding projective arrangements. We generalize theBorel-Serre formula from vector bundles to sheaves on projective d-space withlocally free resolutions of length one. Combining these results we present ageneralization of a formula due to Mustata and Schenck, relating the Poincarepolynomial of an arrangement in projective 3-space (or a locally tamearrangement in projective d-space with zero-dimensional non-free locus) to thetotal Chern polynomial of its sheaf of logarithmic 1-forms.
