The convergence rates, which depend on the scale $\\kappa$ that represents the strength of the singular perturbation and on the length scale $\\epsilon$ of the heterogeneities, are established. We also obtain the large-scale Lipschitz estimate, down to the scale $\\epsilon$ and independent of $\\kappa$. This large-scale estimate, when combined with small-scale estimates, yields the classical Lipschitz estimate that is uniform in both $\\epsilon$ and $\\kappa$.", "revisions": [ { "version": "v1", "updated": "2020-05-26T14:55:46.000Z" } ], "analyses": { "subjects": [ "35B27", "35B25" ], "keywords": [ "singular perturbation", "quantitative estimates", "second-order elliptic systems", "large-scale lipschitz estimate", "singular fourth-order perturbations" ], "note": { "typesetting": "TeX", "pages": 32, "language": "en", "license": "arXiv", "status": "editable" } } }
