As you have heard from Clarence, the Hopf Archive is now a virtual
server on the Purdue Math Department's server.  This means there is no
more ftp access to Hopf, only web access.  Also, because of this
changeover, my October message was a bit delayed.  

3 new papers this month, from Blanc, Devinatz, and Kuhn.

Moduli spaces of homotopy theory

by David Blanc

Dept. of Mathematics, Univ. of Haifa, 31905 Haifa, Israel

  The moduli spaces refered to are topological spaces whose path components
parametrize homotopy types. Such objects have been studied in two separate
contexts: rational homotopy types, in the work of several authors in the late
1970's; and general homotopy types, in the work of Dwyer-Kan and their
collaborators. We here explain the two approaches, and show how they may be
related to each other.

Title: Homotopy groups of homotopy fixed point spectra associated
       to E_n

Author:  Ethan Devinatz

e-mail:  devinatz@math.washington.edu

Abstract:  We compute the mod(p) homotopy groups of the continuous homotopy
H_2 fixed points of E_2 for p>2, where E_n is the Landweber exact spectrum
whose coefficient ring is the ring of functions on the Lubin-Tate moduli
space of lifts of height n formal group laws, and H_n is the semi-direct
product of the group of diagonal matrices in the nth Morava stabilizer
group with an appropriate Galois group. We examine some consequences
of this related to Brown-Comenetz duality and to finiteness properties
of homotopy groups of K(n)_*-local spectra.  We also indicate a plan
for generalizing this computation to n>2.

Title: Goodwillie towers and chromatic homotopy: an overview

Author: Nicholas J. Kuhn

Email:njk4x at virginia.edu
Address: University of Virginia, Charlottesville, VA 22904
arXive no: math.AT/0410342

Abstract: This paper is based on talks I gave in Nagoya and Kinosaki in
August of 2003.  I survey, from my own perspective, Goodwillie's work on
towers associated to continuous functors between topological model
categories, and then include a discussion of applications to periodic
homotopy as in my work and the work of Arone--Mahowald.
