The Helmholtz equation in heterogeneous media: a priori bounds, well-posedness, and resonances

Ivan G. Graham, Owen R. Pembery, Euan A. Spence

We consider the exterior Dirichlet problem for the heterogeneous Helmholtz equation, i.e. the equation $\nabla \cdot (A \nabla u) + k^{2} n u = - f$ where both $A$ and $n$ are functions…
