Multigrid method for nearly singular and slightly indefinite problems [PDF]

open access: yes
This paper deals with nearly singular, possibly indefinite problems for which the usual multigrid solvers converge very slowly or even diverge. The main difficulty is related to some badly approximated smooth functions which correspond to eigenfunctions ...

On the spectral theory of singular indefinite Sturm–Liouville operators

open access: yesJournal of Mathematical Analysis and Applications, 2007
The paper deals with spectral properties of the Sturm-Liouville operator \(A\) associated to an indefinite differential expression of the form \[ \frac{1}{r} \biggl(-\frac{d}{dx} \biggl(p \frac{d}{dx} \biggl) + q\biggl), \] where \(p^{-1},q,r \in L_{\text{loc}}^{1} (\mathbb{R})\) are assumed to be real valued functions such that \(p > 0\) and \(r \neq ...
