| Research Abstract |
The objective of the research project was to consider and develop the mathematical aspects of the point vortex system as a model for two dimensional vortex motions. As one of the characteristics of the model, we have studied the problem of vortex collapse, and extended the 2D self-similar collapse solution into one in three dimensions. We have also studied the statistical properties of stably stratified turbulence as a middle of 2D and 3D turbulence, and investigated the difference in the dimensionality.
