Interpolation scattering for wave equations with singular potentials and singular data
Pham Truong Xuan
In this paper we investigate a construction of scattering for wave-type equations with singular potentials on the whole space in a framework of weak- spaces. Fi…

Geometric scattering for nonlinear wave equations on the Schwarzschild metric
Pham Truong Xuan
In this paper, we establish a conformal scattering theory for defocusing semilinear wave equations on Schwarzschild spacetime. We combine the energy and pointwise decay results for…
