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.
