This theorem also allows one to give companions and refinements of the generalisations of Andrews' theorems to overpartitions. The proof relies on the method of weighted words of Alladi and Gordon and $q$-difference equation techniques introduced recently by the author.", "revisions": [ { "version": "v1", "updated": "2016-06-30T19:24:16.000Z" } ], "analyses": { "keywords": [ "schurs theorem", "companions", "refinements", "unification", "difference equation techniques" ], "note": { "typesetting": "TeX", "pages": 35, "language": "en", "license": "arXiv", "status": "editable" } } }
