On some fundamental concepts of galactic dynamics

On some fundamental concepts of galactic dynamics

We discuss the following fundamental concepts of galactic dynamics: (a) regular (smoothed) and irregular (random) forces, (b) truncation of the impact parameter, (c) the invariance of the Maxwellian velocity distribution, and (d) the Jeans theorem.
