Stabilizing the Hierarchical Basis by Approximate Wavelets II: Implementation and Numerical Results
نویسندگان
چکیده
This paper is the second part of a work on stabilizing the classical hierarchical basis HB by using wavelet-like basis functions. Implementation techniques are of major concern for the multilevel preconditioners proposed by the authors in the first part of the work, which deals with algorithms and their mathematical theory. Numerical results are presented to confirm the theory established there. A comparison of the performance of a number of multilevel methods is conducted for elliptic problems of three space variables.

Stabilizing the Hierarchical Basis by Approximate Wavelets
This paper proposes a stabilization of the classical hierarchical basis (HB)-nite element method by modifying the standard nodal basis functions that correspond to the hierarchical complement (in the next ner discretization space) of any successive coarse dis-cretization space using computationally feasible approximate L 2 {projections onto the given coarse space. The corresponding multilevel a...

This paper proposes a stabilization of the classical hierarchical basis (HB) method by modifying the HB functions using some computationally feasible approximate L2-projections onto finite element spaces of relatively coarse levels. The corresponding multilevel additive and multiplicative algorithms give spectrally equivalent preconditioners, and one action of such a preconditioner is of optima...

متن کاملLegendre Wavelets for Solving Fractional Differential Equations
In this paper, we develop a framework to obtain approximate numerical solutions to ordinary differential equations (ODEs) involving fractional order derivatives using Legendre wavelets approximations. The continues Legendre wavelets constructed on [0, 1] are utilized as a basis in collocation method. Illustrative examples are included to demonstrate the validity and applicability of the techn...
