Uniform approximation of spectra of linear second order differential operators via discrete sine transform based discretisation
We study various discretisation schemes for the regular Sturm--Liouville operator on a bounded interval and for the Laplace operator on an arbitrary planar domain, in both cases subject to zero Dirichlet boundary conditions. The objective is to identify a discretisation scheme such that the corresponding discretised op...
