Improvement by Iteration for Compact Operator Equations
The equation y = / + Ky is considered in a separable Hubert space H, with K assumed compact and linear. It is shown that every approximation to y of the form yXn = £nanl«. (where {u-} is a given complete set in H, and the an¡, 1 < / < n, are arbitrary numbers) is less accurate than the best approximation of the form y2n = f + ZnbnjKUj, if ii is sufficiently large. Specifically it is shown that ...
متن کاملFinite-Rank ADI Iteration for Operator Lyapunov Equations
We give an algorithmic approach to the approximative solution of operator Lyapunov equations for controllability. Motivated by the successfully applied alternating direction implicit (ADI) iteration for matrix Lyapunov equations, we consider this method for the determination of Gramian operators of infinite-dimensional control systems. In the case where the input space is finitedimensional, thi...
متن کاملGeneralized information and maximal order of iteration for operator equations
We consider stationary iterative methods for the solution of operator equations which use "generalized information". We seek methods with maximal order provided the points of iteration are in "good position". The new concepts of order of information and "generalized" interpolatory methods are introduced. The main result states that the maximal order is equal to the order of information which de...
متن کاملSolving time-fractional chemical engineering equations by modified variational iteration method as fixed point iteration method
The variational iteration method(VIM) was extended to find approximate solutions of fractional chemical engineering equations. The Lagrange multipliers of the VIM were not identified explicitly. In this paper we improve the VIM by using concept of fixed point iteration method. Then this method was implemented for solving system of the time fractional chemical engineering equations. The ob...
متن کاملOn the Properties for Iteration of a Compact Operator with Unstructured Perturbation
We consider certain speed estimates for Krylov subspace methods (such as GMRES) when applied upon systems consisting of a compact operator K with small unstructured perturbation B. Information about the decay of singular values of K is also assumed. Our main result is that the Krylov method will perform initially at superlinear speed when applied upon such pre-conditioned system. However, with ...
