A classification of the harmonic frames up to unitary equivalence
, 2011 Up to unitary equivalence, there are a finite number of tight frames of n vectors for Cd which can be obtained as the orbit of a single vector under the unitary action of an abelian group G (for nonabelian groups there may be uncountably many).
