A Group Theoretical Approach to Chaotic Motions


Professor Izaak A. Kunin

Mechanical Engineering Department
University of Houston



Abstract

Group theoretical approach helps to reveal deeply hidden information about basic structures of chaotic motions (order in chaos). The following topics will be discussed:

  1. Interpretation of chaos in terms of flow and density of quasi-dislocations (tensorial curvature).
  2. Complexity and coarse-graining.
  3. Action (orbits) of physically motivated groups of transformations in the phase space of dynamical systems.
  4. The corresponding optimal hierarchy of information levels. G-moving centroidal frames.
  5. Hydrodynamics of phase flows.
  6. Examples of applications to conservative and dissipative systems.
