Manifold structure of spaces of spherical tight frames
Ken Dykema, Nate Strawn
We consider the space F^E_{k,n} of all spherical tight frames of k vectors in real or complex n--dimensional Hilbert space E^n, i.e. E=R or E=C, and its orbit space G^E_{k,n}=F^E_{…

Ellipsoidal tight frames and projection decompositions of operators
Ken Dykema, Dan Freeman, Keri Kornelson +3
We prove the existence of tight frames whose elements lie on an arbitrary ellipsoidal surface within a real or complex separable Hilbert space H, and we analyze the set of attainab…
