Equiangular tight frames that contain regular simplices
Matthew Fickus, John Jasper, Emily J. King +1
An equiangular tight frame (ETF) is a type of optimal packing of lines in Euclidean space. A regular simplex is a special type of ETF in which the number of vectors is one more tha…
A brief introduction to equi-chordal and equi-isoclinic tight fusion frames
Matthew Fickus, John Jasper, Dustin G. Mixon +1
Equi-chordal and equi-isoclinic tight fusion frames (ECTFFs and EITFFs) are both types of optimal packings of subspaces in Euclidean spaces. In the special case where these subspac…
Hadamard Equiangular Tight Frames
Matthew Fickus, John Jasper, Dustin G. Mixon +1
An equiangular tight frame (ETF) is a type of optimal packing of lines in Euclidean space. They are often represented as the columns of a short, fat matrix. In certain applications…
