Integral equation methods for acoustic scattering by fractals
A. M. Caetano, S. N. Chandler-Wilde, X. Claeys +3
We study sound-soft time-harmonic acoustic scattering by general scatterers, including fractal scatterers, in 2D and 3D space. For an arbitrary compact scatterer we reformulate…
Convergent spectral inclusion sets for banded matrices
Simon N. Chandler-Wilde, Ratchanikorn Chonchaiya, Marko Lindner
We obtain sequences of inclusion sets for the spectrum, essential spectrum, and pseudospectrum of banded, in general non-normal, matrices of finite or infinite size. Each inclusion…
On the spectrum of the double-layer operator on locally-dilation-invariant Lipschitz domains
Simon N. Chandler-Wilde, Raffael Hagger, Karl-Mikael Perfekt +1
We say that , the boundary of a bounded Lipschitz domain, is locally dilation invariant if, at each , is either locally or locally coincides (in some coordinat…
