Query: Resonances as viscosity limits for black box perturbations   We show that the complex absorbing potential (CAP) method for computing
scattering resonances applies to an abstractly defined class of black box
perturbations of the Laplacian in $\mathbb{R}^n$ which can be analytically
extended from $\mathbb{R}^n$ to a conic neighborhood in $\mathbb{C}^n$ near
infinity. The black box setting allows a unifying treatment of diverse problems
ranging from obstacle scattering to scattering on finite volume surfaces.
