Abelian and Dihedral equiangular tight frames of redundancy $2$

Radel Ben Av, Xuemei Chen, Assaf Goldberger +1

This paper studies group frames ( $G$ -frames) where the unitary group representation can be projective. When the group is abelian, for most combinations $N, n$ , we show that $ETF(N,…

Phase transitions for frame potentials]{Phase transitions for the minimizers of the $p^{t h}$ frame potentials in $R^{2}$

Radel Ben Av, Xuemei Chen, Assaf Goldberger +2

Given $N$ points $X = {x_{k}}_{k = 1}^{N}$ on the unit circle in $R^{2}$ and a number $0 \leq p \leq \infty$ we investigate the minimizers of the functional $\sum_{k, \ell =1}^N |\…
