The method includes multi correction steps in a sequence of finite element spaces. In each correction step, we only need to solve two source problems on a finer finite element space and two eigenvalue problems on the coarsest finite element space. The accuracy of the eigenpair approximation is improved after each correction step. This correction scheme improves overall efficiency of the finite element method in solving nonsymmetric eigenvalue problems.", "revisions": [ { "version": "v1", "updated": "2015-05-23T08:28:13.000Z" } ], "analyses": { "subjects": [ "65N30", "65N25", "65L15", "65B99" ], "keywords": [ "finite element method", "nonsymmetric eigenvalue problems", "multilevel correction scheme", "coarsest finite element space", "finer finite element space" ], "note": { "typesetting": "TeX", "pages": 17, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2015arXiv150506288X" } } }
