We consider a complete Riemannian manifold, which consists of a compact interior and one or more 𝜑-cusps: infinitely long ends of a type that includes cylindrical ends and hyperbolic cusps. Here, 𝜑 is a function of the radial coordinate that describes the shape of such an end. Given an action by a c...
