For instance, a complete theory of polynomials and power series on $SG$ has been developed by one of us and his coauthors. We build on this body of work to construct certain analogs of classical orthogonal polynomials (OP) on $SG$. In particular, we investigate key properties of these OP on $SG$, including a three-term recursion formula and the asymptotics of the coefficients appearing in this recursion. Moreover, we develop numerical tools that allow us to graph a number of these OP. Finally, we use these numerical tools to investigate the structure of the zero and the nodal sets of these polynomials.", "revisions": [ { "version": "v2", "updated": "2012-07-09T13:06:28.000Z" } ], "analyses": { "subjects": [ "42C05", "28A80", "33F05", "33A99" ], "keywords": [ "sierpinski gasket", "three-term recursion formula", "numerical tools", "complete theory", "power series" ], "note": { "typesetting": "TeX", "pages": 29, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1110.1554O" } } }
