Abstract:

We show that warped cones over actions with spectral gaps do not embed coarsely into large classes of Banach spaces. In particular, there exist warped cones over actions of the free group that do not embed coarsely into $L_p$-spaces, and there are warped cones over discrete group actions that do not embed into any Banach space with non-trivial type.
