On the type of ill-posedness of generalized Hilbert matrices and related operators

Stefan Kindermann

We consider infinite-dimensional generalized Hilbert matrices of the form $H_{i, j} = \frac{d _{i} d _{j}}{x _{i} + x _{j}}$ , where $d_{i}$ are nonnegative weights and $x_{i}$ are pairwise disjoint…

A rational conjugate gradient method for linear ill-conditioned problems

Stefan Kindermann, Werner Zellinger

We consider linear ill-conditioned operator equations in a Hilbert space setting. Motivated by the aggregation method, we consider approximate solutions constructed from linear com…
