Resum
The closure conditions, which make a finite set of moment equations equivalent to the collisionless Boltzmann equation, are investigated for Gaussian and ellipsoidal velocity distributions working from the com- plete mathematical expression for the nth-order stellar hydrodynamic equation, which was explicitly obtained depending on the comoving mo- ments in a previous paper. First, for a Schwarzschild distribution, it is proved that the whole set of hydrodynamic equations is reduced to the equati...
