Techniques for finding bounds on the lowest eigenvalue, 2~, of the problem Au + 2u = 0 in D, Ol . \_2t = On zuon OD(z> 0), are discussed, and some properties of 2t and ui are derived. The problem arises in acoustic propagation in elastic tubes. The lowest eigenvalue is negative, and corresponds to a
The propagation of sound in a resonator is discussed in both the normal and superfluid Fermi liquids. A set of model hydrodynamic equations is developed for describing the transition from the hydrodynamic regime to the collisionless regime. Surface effects are incorporated by using a slip boundary c
