Intersecting Legendrians and blowups
Andrew Hassell, Andras Vasy
The purpose of this note is to describe the relationship between two classes of Legendre distributions. These two classes are distributions associated to an intersecting pair of Le…

The resolvent for Laplace-type operators on asymptotically conic spaces
Andrew Hassell, Andras Vasy
Let X be a compact manifold with boundary, and g a scattering metric on X, which may be either of short range or `gravitational' long range type. Thus, g gives X the geometric stru…

Determinants of Laplacians in Exterior Domains
Andrew Hassell, Steve Zelditch
We consider classes of simply connected planar domains which are isophasal, ie, have the same scattering phase for all . This is a scattering-theoretic analogue of iso…
