| Abstract: | The main difficulties in the study of turbulence via dynamic system lie in how to relate continuum systems of infinite dimension with dynamic system in low dimension space and how to depict its spacial structure. In this paper, we'll give a comprehensive review on various methods to describe complex systems in low dimension space and new approaches to the resolution of turbulence problems. |
