New upper bound for the cardinalities of -distance sets on the unit sphere
arXiv:0906.0195
Abstract
We have the Fisher type inequality and the linear programming bound as upper bounds for the cardinalities of -distance sets on . In this paper, we give a new upper bound for the cardinalities of -distance sets on for any . This upper bound improves the Fisher typer inequality and is useful for -distance sets which are not applicable to the linear programming bound.
