Overview: An arrangement of hyperplanes is a finite collection ofcodimension one affine subspaces in a finite dimensionalvector space. Arrangements haveemerged independently asimportant objects in various fields of mathematics such ascombinatorics, braids, configuration spaces,representationtheory, reflection groups, singularity theory, and incomputer science and physics.This book is the first comprehensive study of the subject.It treats arrangements with methods fromcombinatorics,algebra, algebraic geometry, topology, and group actions.Itemphasizes general techniques which illuminate theconne
