Title:  Poset Fiber Theorems

Abstract:  Suppose that  f: P --> Q is a poset map whose fibers are sufficiently well connected.  We present a result of Bjorner, Wachs, and Welker which gives the homotopy type of P in terms of Q and the fibers, generalizing Quillen's famous fiber lemma.  Applications to homology and subspace arrangements will be covered.  Necessary topological definitions and constructs will be presented.
