Invariant numerical schemes for a heat equation with a logarithmic source and the spherical Burgers equation are obtained. Numerical tests show how invariant schemes can be more accurate than standard discretizations on uniform rectangular meshes.", "revisions": [ { "version": "v1", "updated": "2011-10-26T20:14:39.000Z" } ], "analyses": { "subjects": [ "58J70", "68N06" ], "keywords": [ "partial differential equations", "symmetry preserving numerical schemes", "numerical tests", "preserving finite difference schemes", "symmetry preserving finite difference" ], "note": { "typesetting": "TeX", "pages": 18, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1110.5921R" } } }
