We prove that for a suitable rescaling of this model, the solution converges to the solution of a Peierls-Nabarro model, which is a coupled system of two PDEs (typically an elliptic PDE in a domain with an evolution PDE on the boundary of the domain). This passage from the discrete model to a continuous model is done in the framework of viscosity solutions.", "revisions": [ { "version": "v1", "updated": "2010-10-05T12:31:14.000Z" } ], "analyses": { "keywords": [ "peierls-nabarro model", "coupled first order odes", "viscosity solutions", "elliptic pde", "solution converges" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010arXiv1010.0865F" } } }
