Paulsen Problem for A-admissible Frames
- 25 Downloads
In this paper, we present an algorithm—gradient descent of the frame potential—for increasing the degree of tightness of any finite admissible frame, and show that this algorithm converges to an admissible tight frame. We provide an explicit answer to the generalizations of the Paulsen problem.
