The radiative transport equation with heterogeneous cross-sections
J. C. H. Blake, I. G. Graham, F. Scheben +1
We consider the classical integral equation reformulation of the radiative transport equation (RTE) in a heterogeneous medium, assuming isotropic scattering. We prove an estimate f…

Stability and error analysis for the Helmholtz equation with variable coefficients
I. G. Graham, S. A. Sauter
We discuss the stability theory and numerical analysis of the Helmholtz equation with variable and possibly non-smooth or oscillatory coefficients. Using the unique continuation pr…
