The \\textit{Addendum} was not included in the English translation of the book by technical reasons. I present here the missing translation. In order to make the text self-contained, I have added in the translation the equations from the main body of the book used in the Addendum.", "revisions": [ { "version": "v1", "updated": "2011-11-13T11:49:31.000Z" } ], "analyses": { "keywords": [ "third order", "evolution equations", "lie-bäcklund symmetries", "translation", "group analysis" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1111.3002I" } } }
