Summary

A diverse group of astronomers, physicists, and mathematicians discuss chaos in observational data of variable stars; unstable long wavelenth MHD waves; the interstellar medium; Alfven waves and interstellar turbulence; sinuous oscillations and steady warps of polytropic disks; waves in shock-bounded slabs; normal modes and continuous spectra; vorticity and mixing in disks; bending waves in flattened stellar systems; global wave patterns in galaxies; invariant spectra of dynamical systems time-periodic potentials; Lyapunov numbers in pulsating systems; Arnold diffusion in an oscillator chain; universal properties of escape; counterrotating bars; shadowing and noise in nonhyperbolic systems; relativistic accretion disks; tidal perturbation of a gaseous disk; magnetized accretion disks; structural stability; nonlinear stellar pulsation; tidal pertubations, gravitational amplifacation and galaxy spiral arms; gasous vortices in barred spiral galaxies; and the barred spiral gallaxy NGC 1398. Contributors include J. Robert Buchler, Philip E. Hardee, J.H. Hunter, S. Sridhar, N.J. Balmforth, Ethan T. Vishniac, Philip Yecko, C. Hunter, C.C. Lin, G. Contopoulos, Henry E. Kandrup, Haywood Smith, Allan J. Lichtenberg, Chad L. Davies, Christos V. Siopsis, David E. Willmes, James R. Ipser, J.C.B. Papaloizou, R.V.E. Lovelace, Dimitris M. Christodoulou, Yanqin Wu, Gene Burd, Martin N. England, and E.M. Moore.
