H. Lehmer's conjecture\". Namely, we showed that the m-th Fourier coefficient of the weighted theta series of the $\\mathbb{Z}^2$-lattice and the $A_{2}$-lattice does not vanish, when the shell of norm $m$ of those lattices is not the empty set. In other words, the spherical 4 (resp. 6)-design does not exist among the nonempty shells in the $\\mathbb{Z}^2$-lattice (resp. $A_{2}$-lattice). This paper is the sequel to the previous paper. We take 2-dimensional lattices associated to the algebraic integers of imaginary quadratic fields whose class number is either 1 or 2, except for $\\mathbb{Q}(\\sqrt{-1})$ and $\\mathbb{Q}(\\sqrt{-3})$, then, show that the $m$-th Fourier coefficient of the weighted theta series of those lattices does not vanish, when the shell of norm $m$ of those lattices is not the empty set. Equivalently, we show that the corresponding spherical 2-design does not exist among the nonempty shells in those lattices.", "revisions": [ { "version": "v1", "updated": "2010-04-09T10:43:38.000Z" } ], "analyses": { "subjects": [ "11F03", "05B30" ], "keywords": [ "lehmers conjecture", "toy models", "weighted theta series", "nonempty shells", "empty set" ], "note": { "typesetting": "TeX", "pages": 32, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010arXiv1004.1520B" } } }
