Frames over finite fields: Equiangular lines in orthogonal geometry
Gary R. W. Greaves, Joseph W. Iverson, John Jasper +1
We investigate equiangular lines in finite orthogonal geometries, focusing specifically on equiangular tight frames (ETFs). In parallel with the known correspondence between real E…
Frames over finite fields: Basic theory and equiangular lines in unitary geometry
Gary R. W. Greaves, Joseph W. Iverson, John Jasper +1
We introduce the study of frames and equiangular lines in classical geometries over finite fields. After developing the basic theory, we give several examples and demonstrate finit…
Grassmannian codes from paired difference sets
Matthew Fickus, Joseph W. Iverson, John Jasper +1
An equiangular tight frame (ETF) is a sequence of vectors in a Hilbert space that achieves equality in the Welch bound and so has minimal coherence. More generally, an equichordal…
