A normal form around a Lagrangian submanifold of radial points
Nick Haber
In this work we produce microlocal normal forms for pseudodifferential operators which have a Lagrangian submanifold of radial points. This answers natural questions about such ope…

Propagation of singularities around a Lagrangian submanifold of radial points
Nick Haber, András Vasy
In this work we study the wavefront set of a solution u to Pu = f, where P is a pseudodifferential operator on a manifold with real-valued homogeneous principal symbol p, when the…
