Title: The Paulsen Problem


The Paulsen Problem asks if a frame is nearly tight and nearly equal norm, how close is it to being simultaneously tight and equal norm. This problem has been actively worked on for over ten years now, and still no satisfactory answer has been given. We will give a precise formulation of this problem, and review what is known. We will conclude by giving some recent equivalent reformulations which will hopefully shed some light.
