This workshop will be part of MSRI's Special Semester in Hyperplane Arrangements and Applications. The combinatorial data associated with an arrangement of hyperplanes has proven to be core data for many algebraic and topological issues in arrangement theory. Conversely, the occurrence of certain combinatorial structures in arrangement theory has inspired research on generalizations in purely combinatorial settings. The following topics will be central to the presentations and discussions during this workshop: combinatorial models for arrangements oriented matroids combinatorics of arrangement compactifications phylogenetic trees topology of partially ordered sets combinatorial representation theory random walks on arrangements Confirmed speakers: Christos Athanasiadis Helene Barcelo Ken Brown Graham Denham Persi Diaconis Eva-Maria Feichtner Phil Hanlon Dmitry Kozlov Nikolai Mnev Alexander Postnikov Jessica Sidman Richard Stanley Hiroaki Terao Sasha Varchenko Anatoly Vershik Volkmar Welker Monday, November 1 8:30 - 9:15 Registration 9:15 - 9:30 Welcome and Introduction 9:30 - 10:30 Ken Brown Hyperplane face semigroups and their algebras. 10:30 - 11:00 Morning Tea (Sixth floor) 11:00 - 12:00 Persi Diaconis Are there q-deformations of hyperplanes that are useful for shuffling? 12:00 - 2:00 Lunch Break 3:00 - 4:00 Jessica Sidman, MSRI/Evans Lecture: Equations defining subspace arrangements. 4:15 – 5:00 Richard Stanley, MSRI/Evans Lecture The characteristic polynomial of a hyperplane arrangement.
