Abstract: The halo-mediated inverse cascade is a key feature of the intermediate statistically steady state for self-gravitating collisionless dark matter flow (SG-CFD). How the inverse mass and energy cascade maximize system entropy and develop limiting velocity/energy distributions are fundamental questions to answer. We present a statistical theory concerning the maximum entropy distributions of velocity, speed, and energy for system involving a power-law interaction with an arbitrary exponent $n$. For $-2
