Let $F$ be a frame for $\mathbb{F}^n$, let $\tilde{F}$ be a dual frame, and let $(F,\tilde{F})$ be the associated frame pair. Co-equidistribution characterization conjecture. The f…

Let $F$ be a frame for $\mathbb{F}^n$. A dual of $F$ forms an exclusive Grassmannian pair with $F$ if it is the only dual frame satisfying the paper's Grassmannian coherence minimi…
