Approximation theorems in bilipschitz invariant theory

Jameson Cahill, Joseph W. Iverson, Dustin G. Mixon +1

Bilipschitz invariant theory concerns low-distortion embeddings of orbit spaces into Euclidean space. To date, embeddings with the smallest-possible distortion are known for only a…

On the optimal arrangement of $2 d$ lines in $C^{d}$

Kean Fallon, Joseph W. Iverson

We show the optimal coherence of $2 d$ lines in $C^{d}$ is given by the Welch bound whenever a skew Hadamard of order $d + 1$ exists. Our proof uses a variant of Hadamard dou…
