These polynomials naturally arise in the context of cluster algebras. We conjecture that they are symmetric polynomials in z_1,...,z_n, and that their expansions in terms of monomial, Schur, complete homogeneous, elementary and power sum symmetric polynomials are sign-coherent.", "revisions": [ { "version": "v1", "updated": "2010-08-12T19:28:41.000Z" } ], "analyses": { "keywords": [ "cluster algebras", "strong sign-coherency", "power sum symmetric polynomials", "application", "polynomial functions" ], "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010arXiv1008.2194L" } } }
