单位球面上$s$ -距离集基数的新上界
New upper bound for the cardinalities of $s$-distance sets on the unit sphere
摘要:
我们用Fisher型不等式和线性规划界作为$S^{d-1}$上$s$ -距离集基数的上界。本文对任意$s$,给出了$S^{d-1}$上$s$ -距离集基数的一个新的上界.这个上界改进了Fisher型不等式,并且对于不适用于线性规划界的$s$ -距离集是有用的.
英文摘要:
We have the Fisher type inequality and the linear programming bound as upper bounds for the cardinalities of $s$-distance sets on $S^{d-1}$. In this paper, we give a new upper bound for the cardinalities of $s$-distance sets on $S^{d-1}$ for any $s$. This upper bound improves the Fisher typer inequality and is useful for $s$-distance sets which are not applicable to the linear programming bound.
