New a priori FEM error estimates for eigenvalues by Andrew V Knyazev ( )
2 editions published in 2004 in English and held by 2 WorldCat member libraries worldwide
"We analyze the Ritz method for symmetric eigenvalue problems and prove a priori eigenvalue error estimates. For a single eigenvalue, we prove an error estimate that depends mainly on just the approximability of the corresponding eigenfunction and provide explicit values for all constants. For a multiple eigenvalue we prove, in addition, apparently the first truly a priori error estimates that show the levels of the eigenvalue errors depending on approximability of eigenfunctions in the corresponding eigenspace."--Authors' abstract
Eigenvalue Problems by Ivo Babuška ( Book )
1 edition published in 1987 in English and held by 1 WorldCat member library worldwide
This section presents several model eigenvalue problems arising in physics and engineering. Specifically discussed are some important physical interpretations of eigenvalues and eigenfunctions. Some of the model problems discussed here will serve as illustrative examples in connection with the approximation methods considered later. A clear understanding of the fundamental ideas is presented, but not a detailed treatment. For a more complete discussion of the material in this section refer to Courant-Hilbert 1953
