A new approach to analyticity of Dirichlet-Neumann operators

A new approach to analyticity of Dirichlet-Neumann operators

This paper outlines the theoretical background of a new approach towards an accurate and well-conditioned perturbative calculation of Dirichlet-Neumann operators (DNOs) on domains that are perturbations of simple geometries. Previous work on the analyticity of DNOs has produced formulae that, as we have found, are very ill-conditioned. We show how …
