Fredholm Theory of Non-Elliptic Operators in the Presence of Normally Hyperbolic Trapping
Selim Amar
We present an improved Fredholm theory of non-elliptic operators for when the corresponding classical dynamical system exhibits normally hyperbolic trapping with smooth backward an…

A peeling theorem for the Weyl tensor in higher dimensions
Selim Amar
A peeling theorem for the Weyl tensor in higher dimensional Lorentzian manifolds is presented. We obtain it by generalizing a proof from the four dimensional case. We derive a gene…
