### The smooth Whitehead spectrum of a point at odd regular primes, by John Rognes

Let p be an odd regular prime, and assume that the Lichtenbaum--Quillen
conjecture holds for K(Z[1/p]) at p. Then the p-primary homotopy type
of the smooth Whitehead spectrum Wh(*) 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
S^1-transfer map t : \Sigma C P^\infty \to S. The homotopy of Wh(*) is
determined in a range of degrees, and the cohomology of Wh(*) is expressed
as an A-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.
