We prove essential self-adjointness for semi-bounded below magnetic Schrödinger operators on complete Riemannian manifolds with a given positive smooth measure which is fixed independently of the metric. Some singularities of the scalar potential are allowed. This is an extension of the Povzner-Wien

A theoretical framework is developed for constructing spectral refinement schemes for a simple eigenelement which achieve arbitrarily high rates of convergence while keeping the computational cost at a minimum. The new approach is illustrated by considering a Newton type iteration scheme. Numerical
