【 摘 要 】

This document constitutes the final report for the grant. It provides a complete list of publications and presentations that arose from the project as well as a brief description of the highlights of the research results. The research funded by this grant has provided insights into the spontaneous formation of structures of increasing complexity in systems driven far from thermodynamic equilibrium. A classic example of such a system is thermally driven convection in a horizontal fluid layer. Highlights of the research are: (i) explanation of the localized traveling wave pulses observed in binary-mixture convection, (ii) explanation of the localized waves in electroconvection, (iii) introduction of a new diagnostics for spatially and temporally chaotic states, which is based on the statistics of defect trajectories, (iv) prediction of complex states in thermally driven convection in rotating systems. Additional contributions provided insight into the localization mechanism for oscillons, the prediction of a new localization mechanism for traveling waves based on a resonant periodic forcing, and an analysis of the stability of quasi-periodic patterns.
