DESCRIPTION:This talk is regarding PDE systems from geophysical applicatio
 ns with multiple time scales\, in which linear skew-self-adjoint operators
  of size 1/epsilon gives rise to highly oscillatory solutions. Analysis is
  performed in justifying the limiting dynamics as epsilon goes to zero\; f
 urthermore\, the analysis yields estimates on the difference between the m
 ultiscale solution and the limiting solution. We will introduce a simple y
 et effective time-averaging technique which is especially useful in genera
 l domains where Fourier analysis is not applicable.
