Bordifications of hyperplane arrangements and their curve complexes

چکیده

The complement of an arrangement hyperplanes in $\mathbb C^n$ has a natural bordification to manifold with corners formed by removing (or "blowing up") tubular neighborhoods the and certain their intersections. When is complexification real simplicial arrangement, closely resembles Harvey's moduli space. We prove that faces universal cover are parameterized simplices complex $\mathcal{C}$, vertices which irreducible "parabolic subgroups" fundamental group complement. So, $\mathcal{C}$ plays similar role for as curve does Also, analogy complexes spherical buildings, we homotopy type wedge spheres.

Deformations of Coxeter hyperplane arrangements and their characteristic polynomials

Let A be a Coxeter hyperplane arrangement, that is the arrangement of reflecting hyperplanes of an irreducible finite Coxeter group. A deformation of A is an affine arrangement each of whose hyperplanes is parallel to some hyperplane of A. We survey some of the interesting combinatorics of classes of such arrangements, reflected in their characteristic polynomials.

Random Walk and Hyperplane Arrangements

Let C be the set of chambers of a real hyperplane arrangement. We study a random walk on C introduced by Bidigare, Hanlon, and Rockmore. This includes various shuuing schemes used in computer science, biology, and card games. It also includes random walks on zonotopes and zonotopal tilings. We nd the stationary distributions of these Markov chains, give good bounds on the rate of convergence to...

Branched Polymers and Hyperplane Arrangements

We generalize the construction of connected branched polymers and the notion of the volume of the space of connected branched polymers studied by Brydges and Imbrie [BI], and Kenyon and Winkler [KW] to any hyperplane arrangement A. The volume of the resulting configuration space of connected branched polymers associated to the hyperplane arrangement A is expressed through the value of the chara...

Artin groups and hyperplane arrangements

These are the notes of a mini-course given at the conference “Arrangements in Pyrénées”, held in Pau (France) from 11th to 15th of June, 2012. Definition. Let S be a finite set. A Coxeter matrix on S is a square matrix M = (ms,t)s,t∈S indexed by the elements of S and satisfying: (a) ms,s = 1 for all s ∈ S; (b) ms,t = mt,s ∈ {2, 3, 4, . . . } ∪ {∞} for all s, t ∈ S, s 6= t. A Coxeter matrix is u...

Hyperplane Arrangements: Computations and Conjectures

This paper provides an overview of selected results and open problems in the theory of hyperplane arrangements, with an emphasis on computations and examples. We give an introduction to many of the essential tools used in the area, such as Koszul and Lie algebra methods, homological techniques, and the Bernstein-Gelfand-Gelfand correspondence, all illustrated with concrete calculations. We also...
