Abstract
The stability of differentially rotating fluid cylinders is re-examined. One kind of instability occurring is shown to be due to resonant interaction of modes belonging to different boundaries. A detailed description of the mode interaction is given applicable both to surface and sound waves. We classify the modes due to their physical origin and provide a general scheme of their order. The second kind of instability is due to energy loss from the system, in particular due to acoustic radiation. A physical interpretation is given for both of the instabilities in terms of the energy of a mode.
