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 fre…

In this paper we investigate generalizations of Kazhdan's property to the setting of uniformly convex Banach spaces. We explain the interplay between the existence of spectra…
