DESCRIPTION:Many groups admit an affine action on a Hilbert\,
or suitable Banach space which is proper\, or at l
east has an unbounded orbit. For example\, CAT(0)
cubical groups act properly on Hilbert space\; and
a hyperbolic group acts properly on an Lp-space\,
although some cannot act on a Hilbert space with
an unbounded orbit (or even without a global fixed
point). In the talk I will describe these results
and will discuss some recent work\, joint with Er
ic Reckwerdt and Romain Tessera\, on the existence
of affine actions of relatively hyperbolic groups
.
