DESCRIPTION:Speakers: Peter Symonds (Manchester)\nWe consider a finite gro
up G acting on a polynomial ring k[V] and try to understand the multiplici
ty of a given indecomposable kG-summand in terms of commutative algebra. W
e then try and do the same for cohomology of a group\, considering it as a
Mackey functor on the subgroups of G.\n\nhttps://indico.math.cnrs.fr/even

DESCRIPTION:Speakers: Niko Naumann (Regensburg)\nWe will report on joint w
ork (partially in progress) with Akhil Mathew and Justin Noel about descen
t in an equivariant context. This allows to revisit and extend various cla
ssical results of Quillen\, Hopkins/Kuhn/Ravenel\, and Thomason and leads
to a number of interesting questions and conjectures.\n\nhttps://indico.ma

DESCRIPTION:Speakers: Christine Vespa (Strasbourg)\nFunctor homology (i.e.
homological algebra in functor categories) on a suitable category allow u
s to compute some stable homology of linear groups\, orthogonal groups or
symplectic groups with twisted coefficients. \n\nLittle is known concernin
g stable homology of automorphism groups of free groups with twisted coeff
icients. We have cancellation results\, several computations in small degr
ee by Satoh and explicit classes constructed by Kawazumi. Homology of func
tors from groups to abelian groups should help us to better understand sta
ble homology of automorphism groups of free groups with twisted coefficien
ts. \n\nIn this talk\, I will explain the previous motivation for the stud
y of homology of functors from groups to abelian groups and I will give se
veral results concerning this functor homology.\n\nhttps://indico.math.cnr

DESCRIPTION:Speakers: Gerd Laures (Bochum)\nWe develop a theory of charact
eristic classes for the cohomology of topological modular forms with \\Gam
ma_0(3)-level structures. These classes are supposed to play an important
role in the determination of the string bordism ring. It turns out that th
e TMF_0(3)-cohomology of BString is freely generated by Pontryagin classes
and one extra class which relates to the theory of cubical structures for
line bundles on elliptic curves.\n\nhttps://indico.math.cnrs.fr/event/596

DESCRIPTION:Speakers: Paul Goerss (Northwestern)\nSome time ago\, Goerss\,
Henn\, Mahowald\, and Rezk produced a topological resolution of the K(2)-
local sphere at the prime 3. Along with the emergence of topological modul
ar forms\, this was one of the events that helped organize our thinking ab
out the entire K(2)-local category. The occasion of this conference seems
a good time to revisit these constructions and some of the theorems that f
ollowed\, both new and old.\n\nhttps://indico.math.cnrs.fr/event/596/contr

DESCRIPTION:Speakers: Mark Behrens (Notre Dame)\nThis talk represents join
t work with Kyle Ormsby\, Nat Stapleton\, and Vesna Stojanoska. \n\nI will
describe 3 different perspective on tmf_*tmf (localized at 2).\n(1) the E
_2-term of the Adams spectral sequence for tmf_*tmf decomposes as a direct
sum of ext groups associated to bo-Brown-Gilter modules\, \n(2) modulo to
rsion\, tmf_*tmf embeds into the ring of 2-variable modular forms\, and \n
(3) modulo v_2-torsion\, tmf_*tmf embeds into a product of TMF_0(N)_*\, fo
r various values of N\, and how they are related.\n\nhttps://indico.math.c

DESCRIPTION:Speakers: Lionel Schwartz (Paris 13)\nS. Takaysu introduced ce
rtain cofiber sequences which generalize the identification of a stunted i
nfinite projective space with a certain Thom space. These sequences occur
within the context of the Arone-Goodwillie tower for\nexample. We will des
cribe a new construction of these sequences. The construction uses certain
properties of Lannes' T functor which will be discussed.\n \n(joint work

UID:indico-contribution-596-2200@indico.math.cnrs.fr
DESCRIPTION:Speakers: John Greenlees (Sheffield)\nIt is elementary that ku
(with coefficients Z[v]) is Gorenstein of shift -3.\nIt follows that KU (
with coefficients Z[v\, 1/v]) is Anderson self-dual (with shift one more)
and by descent that ko is Gorenstein of shift -5 and KO is Anderson self-d
ual (of shift one more).\n\nThere are a number of similar examples arising
from topological modular (tmf(2)\, tmf(3)) and automorphic forms. The tal
k will describe the general context\, how to predict the change in shifts
under descent\, and some particular cases (Joint work with Vesna Stojanosk
a).\n\nhttps://indico.math.cnrs.fr/event/596/contributions/2200/

DESCRIPTION:Speakers: Vesna Stojanoska (MPI Bonn)\nFor a finite subgroup G
of the Morava stabilizer group of height n at a prime p\, there is an ass
ociated ring spectrum EO = (E_n)^{hG} of homotopy fixed points of Morava E
-theory E_n under its G-action. The spectra EO carry some tractable inform
ation about the K(n)-local sphere. We study their Picard groups\, and show
that\, when n=p-1\, Pic(EO) is always cyclic. This is joint work with Dre
w Heard and Akhil Mathew.\n\nhttps://indico.math.cnrs.fr/event/596/contrib
