| Outline of Final Research Achievements |
In this project, we have investigated the mechanisms for collective motions, reactions, and functions of complex molecular systems on the basis of statistical mechanics, nonlinear dynamics, and geometry. We have clarified the driving mechanisms for oblate-prolate structural transitions and dissociations of atomic clusters. We have also clarified asymmetric elasticity of biomolecules such as DNA and its significance in the formation of higher-order structures. Moreover, we have studied the mechanisms for the transport of asteroids between local equilibria based on the dynamical analogy between molecular systems and planetary systems.
