The representation theory of these algebras $\\mathsf{b}_{n,k}(\\beta=q+q^{-1})$ is given: their irreducible, standard (cellular) and principal modules are constructed and their structure explicited in terms of their composition factors and of non-split short exact sequences. The dimensions of the irreducible modules and of the radicals of standard ones are also given. The methods proposed here might be applicable to a large family of algebras, for example to those introduced recently by Flores and Peltola, and Cramp\\'e and Poulain d'Andecy.", "revisions": [ { "version": "v1", "updated": "2019-09-08T16:29:55.000Z" } ], "analyses": { "keywords": [ "representation theory", "non-split short exact sequences", "boundary seam algebras", "two-dimensional statistical loop models", "poulain dandecy" ], "note": { "typesetting": "TeX", "pages": 29, "language": "en", "license": "arXiv", "status": "editable" } } }
