| Outline of Final Research Achievements |
Spatiotemporal chaos is characterized by the the coexistence of local order and global disorder. Experimental researches on spatiotemporal chaos appearing in electroconvection of a nematic liquid crystal have been done in order to discuss transport phenomena and fluctuation-dissipation relation in fluctuations due to the spatiotemporal chaos. Memory functions which are generalized friction coefficients were obtained by data analysis techniques in order to describe the fluctuations by generalized Langevin equation which is a theory for properties of fluctuations. Moreover, information for chaos-induced friction was obtained by responses of spatiotemporal chaos to external forces. From these results, it was clarified that fluctuations of spatiotemporal chaos show hierarchical transport phenomena which reflect the coexistence of local order and global disorder.
