Line-closed matroids, quadratic algebras, and formal arrangements
Michael Falk
Let be a matroid on ground set \A. The Orlik-Solomon algebra is the quotient of the exterior algebra \E on \A by the ideal \I generated by circuit boundaries. The quadra…
Combinatorial and algebraic structure in Orlik-Solomon algebras
Michael Falk
The Orlik-Solomon algebra of a matroid is the free exterior algebra on the points, modulo the ideal generated by the circuit boundaries. On one hand, this algebra…
On the homotopy theory of arrangements, II
Michael Falk, Richard Randell
In "On the homotopy theory of arrangements," published in 1986, the authors gave a comprehensive survey of the subject. This article updates and continues the earlier article, noti…
Parallel connections and bundles of arrangements
Michael J. Falk, Nicholas J. Proudfoot
Let \A be a complex hyperplane arrangement, and let be a modular element of arbitrary rank in the intersection lattice of \A. We show that projection along restricts to a f…
