Query: Should Elliptical Galaxies Be Idealised as Collisionless Equilibria?   This talk summarises several different lines of argument suggesting that one

collisionless equilibria, i.e., that such objects should not be idealised as
time-independent solutions to the collisionless Boltzmann equation.
