Garau", "Pedro Morin", "Carlos Zuppa" ], "categories": [ "math.NA" ], "abstract": "We design an adaptive finite element method to approximate the solutions of quasi-linear elliptic problems. The algorithm is based on a Ka\\v{c}anov iteration and a mesh adaptation step is performed after each linear solve. The method is thus \\emph{inexact} because we do not solve the discrete nonlinear problems exactly, but rather perform one iteration of a fixed point method (Ka\\v{c}anov), using the approximation of the previous mesh as an initial guess. The convergence of the method is proved for any \\emph{reasonable} marking strategy and starting from any initial mesh. We conclude with some numerical experiments that illustrate the theory.", "revisions": [ { "version": "v1", "updated": "2010-06-16T20:14:20.000Z" } ], "analyses": { "keywords": [ "adaptive kačanov fem", "quasi-linear problems", "convergence", "adaptive finite element method", "quasi-linear elliptic problems" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010arXiv1006.3319G" } } }
