This lecture covers the dispersion relation for fluids and rotating stellar sheets, the response of systems to perturbations, the stability of uniform rotating systems, and the origin of spiral structures in galaxies. It discusses the Jeans instability, the stabilizing effects of shearing motions, and the number of spiral arms in rotating disks.
