Abstract
Let be an odd regular prime, and assume that the Lichtenbaum–Quillen conjecture holds for at . Then the –primary homotopy type of the smooth Whitehead spectrum is described. A suspended copy of the cokernel-of-J spectrum splits off, and the torsion homotopy of the remainder equals the torsion homotopy of the fiber of the restricted -transfer map . The homotopy groups of are determined in a range of degrees, and the cohomology of is expressed as an -module in all degrees, up to an extension. These results have geometric topological interpretations, in terms of spaces of concordances or diffeomorphisms of highly connected, high dimensional compact smooth manifolds.
