Nonexistence of tight spherical design of harmonic index 4

Takayuki Okuda, Wei-Hsuan Yu

We give a new upper bound of the cardinality of a set of equiangular lines in $R^{n}$ with a fixed angle $θ$ for each $(n, θ)$ satisfying certain conditions. Our techniques are based…

Finite two-distance tight frames

Alexander Barg, Alexei Glazyrin, Kasso Okoudjou +1

A finite collection of unit vectors $S \subset R^{n}$ is called a spherical two-distance set if there are two numbers $a$ and $b$ such that the inner products of distinct ve…
