The mathematical theory of Krylov subspace methods with a focus on solving systems of linear algebraic equations is given a detailed treatment in this principles-based book. Starting from the idea of projections, Krylov subspace methods are character

Operator preconditioning based on decomposition into subspaces has been developed in early 90’s in the works of Nepomnyaschikh, Matsokin, Oswald, Griebel, Dahmen, Kunoth, Rude, Xu, and others, with inspiration from particular applications, e.g., to

The Stieltjes problem of moments seeks for a nondecreasing positive distribution function μ ( λ ) on the semi-axis [ 0 , + ∞ ) so that its moments match a given infinite sequence of positive real numbers m 0 , m 1 , … . In his seminal paper Inv

We analyze the spectrum of the operator $\Delta^{-1} [\nabla \cdot (K\nabla u)]$, where $\Delta$ denotes the Laplacian and $K=K(x,y)$ is a symmetric tensor. Our main result shows that this spectrum can be derived from the spectral decomposition $K=Q
