The High Energy Distribution of Scattering Phase Shifts of Schrödinger operators in Hyperbolic Space
Antônio Sá Barreto
We prove a trace formula for the high energy limit of the scattering phase shifts of Schrödinger operators with short range real valued potentials in hyperbolic space; it relates t…

Recovery of a general nonlinearity in the semilinear wave equation
Antônio Sá Barreto, Plamen Stefanov
We study the inverse problem of recovery a non-linearity , which is compactly supported in , in the semilinear wave equation . We probe the medium w…
