Workshop on "Combinatorial and geometric aspects of Hyperplane Arrangements" May 24th through 26th

MAY WORKSHOP: Brunnian braids and homomorphisms of arrangement groups

speaker: Michael Falk (Northern Arizona University, Flagstaff)

abstract: We describe a generalization of Stanford's theorem characterizing Brunnian braids, and give an application to fundamental groups of complements of complex hyperplane arrangements. In some cases one is able to show these arrangement groups are subdirect products of free groups, and draw conclusions about their residual properties and homological finiteness type. This is joint work with Daniel C. Cohen and Richard Randell.
