Homotopical Group Theory and Topological Algebraic Geometry
This workshop is aimed at graduate students and young researchers, in
part as preparation for the
at the Max Planck institute the following week. The
workshop, as well as conference, focuses on the new interactions of Algebraic Topology with
Group Theory, Algebraic Geometry and Mathematical Physics which come
from looking at these fields through the eye of a homotopy
theorist. It celebrates one of the contributors to the subject by
honoring the 60th birthday of Haynes Miller.
NEW (July 9,2008): Workshop pictures!!
Minicourse by Bill Dwyer (Notre Dame): Homotopical group theory
(10 lectures of 45 minutes each).
Minicourse by Paul Goerss (Northwestern): Topological algebraic
geometry (10 lectures of 45 minutes each).
In addition to the lectures there will be scheduled problem sessions
each day on both topics. Several of the MPI speakers will be in
residence to answer questions (Behrens, Lurie...)

Getting to CabInn Scandinavia and the Univ. Copenhagen Math
Department/H.C.Ørsted Institute (in "Universitetsparken")
To get to CabInn
Scandinavia from the airport, take the frequent metro from the
airport terminal and get off at the stop "Forum" (17 minutes, 10 stops; every metro from the airport stops at
"Forum"). CabInn Scandinavia is now very close. For a map and more detailed directions see here.
You need to buy
a 3 zone ticket in the airport terminal before boarding the
metro (or buy and stamp a 10 journey 3-zone multijourney
Getting from CabInn Scandinavia to the Math Department/The
H.C. Ørsted Institute (HCØ) is a
pleasant 30 minutes walk (metro/bus is also an option). See the directions page for a map.
Within HCØ, all lectures take place in the central Auditorium 1. A map of the HCØ
indicating the location of Auditorium 1 can
be found here
A more fancy google map, also showing bus stops and lunch places can
(but don't worry, there
will also be signs, and 120 topologists running around).

Homotopy theory and its application to classifying spaces (Bill Dwyer)
Synopsis: The lectures will introduce several tools that are widely
used in homotopy theory and discuss the role that some of these tools
play in the analysis of classifying spaces. Much of the course will
focus on unstable homotopy theory, and the intention will be to
emphasize common ideas rather than special cases. The topics covered
will include many if not all of the following.
(1) Homotopy theories, model categories, and examples (chain
complexes, topological spaces, simplicial sets, topological
groups, simplicial groups, spectra, diagrams).
(2) Functors, derived functors, and examples (tensor, hom,
abelianization, fixed point sets, orbits, limits, colimits,
left and right Kan extensions, ends and coends). Initial and
terminal functors. Function spaces.
(3) Completions, localizations, and examples (p-completion,
rationalizaton, general homology localization, localization
with respect to a map). The arithmetic square and its
(4) Lannes theory, both algebra (the functor T) and geometry
(towers and their limits). Cohomology of function spaces and
homotopy fixed point sets.
(5) K(\pi,1)'s and maps between them. More general maps between
classifying spaces. Compact Lie groups, finite loop spaces,
(6) Homology decompositions, fusion systems, and p-local finite
Prerequisites: It will be assumed that the members of the audience
have a background in the basics of

Topological algebraic geometry (Paul Goerss)
Synopsis: I would like to give a concise introduction to derived
algebraic geometry over the moduli stack of
formal groups. Put another way, I would like to discuss when
continuous families of Landweber exact homology
theories can be lifted to families of structured ring spectra. I would
also like to explain why we care:
this is part of long standing program (going back to Morava and
others) of using arithmetic algebraic
geometry to understand phenomena in stable homotopy theory. While very
much a developing theory, the work of
Hopkins, Miller, Lurie, Behrens, Lawson, and others over the last ten
or so years have given us very precise
tools. The theory and practice of these tools is the emphasis of these
Topics we be a subset of the following list, depending on time and
the background of the audience.
1. Schemes, stacks, and algebraic stacks
2. Structured ring spectra and derived algebraic geometry
3. Formal groups, p-divisible groups, and their role in homotopy
4. Derived stacks over the moduli stack of formal groups; Lurie's
5. Deformations of formal groups and the Hopkins-Miller theorem
6. Examples: the Elliptic Case (Topological Modular Forms)
7. Examples: Shimura varieties (Topological Automorphic Forms)

Registration & application for funding
THE REGISTRATION DEADLINE HAS NOW PASSED. See further down the page
for funding decisions.
A list of registred participants is available from the
Conference website. (It should say "Yes" in the column
"Reg. CO" if you are registered for Copenhagen.)
Accomodation in Copenhagen will be at CABINN SCANDINAVIA. The
price is DKK 585/night for a single room and DKK 645/night (approx
EUR 86) for a double room, including breakfast.
A block of rooms has been reserved for 7 nights from Sunday June 15,
2008 to Sunday June 22, 2008. Note: Talks starts Monday morning
and end Friday afternoon; there will be a social program
**PARTICIPANTS ARE RESPONSIBLE FOR BOOKING THEIR OWN ACCOMODATION AT CABINN SCANDINAVIA** by calling (+45) 35 36 11 11 and citing the booking reference #100253.
Hotel space at Cab Inn only guaranteed until FEBRUARY 15, 2008.
As of late February there are still rooms available at CabInn. But
we cannot guarantee future availability, so please book today.

2008 in the morning and end Friday June 20 in the

For people traveling onwards to Bonn, there are frequent flights between Copenhagen (CPH)
and Cologne/Bonn (CGN), Frankfurt (FRA), or Dusseldorf
(DUS). Overseas participants attending both events may want to
consider buying an "open-jaw" ticket arriving in Copenhagen Sunday June 15 and
departing from e.g. Frankfurt Saturday June 29, and then buy the
one-way Copenhagen-Bonn on June 21 or 22 separately.

the route network of low-cost carriers within Europe.)
The conference is partially supported by the DFG
Graduiertenkolleg 1150 "Homotopy and Cohomology" , the Max Planck Institute
Bonn., and the US National Science Foundation.
The workshop is supported by the
University of Copenhagen through a grant from the researcher training program
"Forskerskole i Matematik og anvendelser" and a Faculty of Science
grant, as well as a EURYI award from the ESF and Roemer
award from the Danish Natural Science Research Council.
The workshop is organized by the Copenhagen Topology
Group, in connection with the conference at MPI organized by Ando,
Grodal, Laures, and Shipley.
