The Largest Intersection Lattice of a Discriminantal Arrangement
نویسنده
چکیده
We prove a conjecture of Bayer and Brandt J. Alg. Combin. 6 (1997), 229{246] about the \largest" intersection lattice of a discriminantal arrangement based on an essential arrangement of n linear hyperplanes in R k. An important ingredient in the proof is Crapo's characterization of the matroid of circuits of the connguration of n generic points in R k .

متن کاملDiscriminantal Arrangements, Fiber Polytopes and Formality
Manin and Schechtman defined the discriminantal arrangement of a generic hyperplane arrangement as a generalization of the braid arrangement. This paper shows their construction is dual to the fiber zonotope construction of Billera and Sturmfels, and thus makes sense even when the base arrangement is not generic. The hyperplanes, face lattices and intersection lattices of discriminantal arrange...
متن کاملOn the Cohomology of Discriminantal Arrangements and Orlik-solomon Algebras
We relate the cohomology of the Orlik-Solomon algebra of a discriminantal arrangement to the local system cohomology of the complement. The Orlik-Solomon algebra of such an arrangement (viewed as a complex) is shown to be a linear approximation of a complex arising from the fundamental group of the complement, the cohomology of which is isomorphic to that of the complement with coefficients in ...
متن کاملOn Horn-Kapranov uniformisation of the discriminantal loci
In this note we give a rational uniformisation equation of the discriminant loci associated to a non-degenerate affine complete intersection variety. To show this formula we establish a relation of the fibre-integral with the hypergeometric function of Horn and that of Gel’fand-Kapranov-Zelevinski. 0 Introduction In this note we give a concrete rational uniformisation equation for the discrimin...
متن کاملThe Face Semigroup Algebra of a Hyperplane Arrangement
This article presents a study of an algebra spanned by the faces of a hyperplane arrangement. The quiver with relations of the algebra is computed and the algebra is shown to be a Koszul algebra. It is shown that the algebra depends only on the intersection lattice of the hyperplane arrangement. A complete systemof primitive orthogonal idempotents for the algebra is constructed and other algebr...
