Abstract: Fix a finite connected CW complex of dimension . An thickening of is a pair in which is a compact dimensional manifold and is a simple homotopy equivalence. This concept was first introduced by C.T.C. Wall approximately 40 years ago. Most of the known results about thickenings are in a range of dimensions depending on , and the connectivity of . In this paper we remove the connectivity hypothesis on . We define moduli space of thickenings . We also define a suspension map and compute its homotopy fibers in a range depending only on and . We will show that these homotopy fibers can be approximated by certain section spaces whose definition depends only on the choice of a certain stable vector bundle over .
