Analysis of quasi-Monte Carlo methods for elliptic eigenvalue problems with stochastic coefficients
Alexander D. Gilbert, Ivan G. Graham, Frances Y. Kuo +2
We consider the forward problem of uncertainty quantification for the generalised Dirichlet eigenvalue problem for a coercive second order partial differential operator with random…

Domain Decomposition with local impedance conditions for the Helmholtz equation with absorption
I. G. Graham, E. A. Spence, J. Zou
We consider one-level additive Schwarz preconditioners for a family of Helmholtz problems with absorption and increasing wavenumber . These problems are discretized using the Ga…

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 where both and are functions…
