For such a crystal $K$ with colors $1,2,...,n$, we consider its maximal connected subcrystals with colors $1,...,n-1$ and with colors $2,...,n$ and characterize the interlacing structure for all pairs of these subcrystals. This is used to give a recursive description of the combinatorial structure of $K$ and develop an efficient procedure of assembling $K$.", "revisions": [ { "version": "v1", "updated": "2012-12-23T08:12:09.000Z" } ], "analyses": { "subjects": [ "17B37", "05C75", "05E99" ], "keywords": [ "assembling crystals", "maximal connected subcrystals", "quantized universal enveloping algebra", "combinatorial structure", "efficient procedure" ], "note": { "typesetting": "TeX", "pages": 24, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2012arXiv1212.5771D" } } }
