Absence of super-exponentially decaying eigenfunctions on Riemannian manifolds with pinched negative curvature
Andras Vasy, Jared Wunsch
Let (X,g) be a metrically complete, simply connected Riemannian manifold with bounded geometry and pinched negative curvature, i.e. there are constants a>b>0 such that -a^2<K<-b^2…

Lipschitz domains, domains with corners and the Hodge Laplacian
Marius Mitrea, Michael Taylor, Andras Vasy
We define self-adjoint extensions of the Hodge Laplacian on Lipschitz domains in Riemannian manifolds, corresponding to either the absolute or the relative boundary condition, and…

Propagation of singularities for the wave equation on manifolds with corners
Andras Vasy
In this paper we describe the propagation of smooth (C^\infty) and Sobolev singularities for the wave equation on smooth manifolds with corners M equipped with a Riemannian metric…
