The Lower Bounds of Eigenvalues by the Wilson Element in Any Dimension
Authors:Youai Li
Abstract:
In this paper, we analyze the Wilson element method of the eigenvalueproblem in arbitrary dimensions by combining a new technique recentlydeveloped in [10] and the a posteriori error result. Weprove that the discrete eigenvalues are smaller than the exact ones.
Keywords:The lower approximation   the Wilson element   the eigenvalue problem.
