On the Numerical Stability Analysis of Pipelined Krylov Subspace Methods
Algebraic solvers based on preconditioned Krylov subspace methods are among the most powerful tools for large scale numerical computations in applied mathematics, sciences, technology, as well as in emerging applications in social sciences. The study of mathematical properties of Krylov subspace methods, in both the cases of exact and inexact computations, is a very active area of research and ...
متن کاملConvergence analysis of Krylov subspace methods †
One of the most powerful tools for solving large and sparse systems of linear algebraic equations is a class of iterative methods called Krylov subspace methods. Their significant advantages like low memory requirements and good approximation properties make them very popular, and they are widely used in applications throughout science and engineering. The use of the Krylov subspaces in iterati...
متن کاملStability of Krylov Subspace Spectral Methods
This talk summarizes recent analysis of an alternative approach to the solution of diffusion problems and wave propagation problems in the variable-coefficient case that leads to a new class of numerical methods, called Krylov subspace spectral methods [3]. The basic idea behind these methods, applied to a PDE of the form du/dt + L(x,D)u = 0, is to use Gaussian quadrature in the spectral domain...
