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/
