New Challenges in Complex Systems Science


Studies on complex systems have lately attracted considerable attention, with the expectation to bring about a breakthrough in interdisciplinary subjects of contemporary science and technology.

The origin of complexity is of common interest; not only to elucidate the detailed pathways leading to complex aspects in structures, processes, and functions of the whole system, but also to surmount the limit of unpredictable complexity towards new technologies on the human environment. Recent developments in nonlinear mathematics and physics also enable us to challenge the modeling of complex subjects, and successfully to discover universal features in complex phenomena as well as exotic ones beyond prerequisite ideas.

This symposium and seminar aims to discuss new challenges and trends in diversely-growing complex systems science. Invited papers focus on the new results in their own fields, but emphasize the intrinsic mechanisms in complex phenomena. Discussions are promoted for all participants with different backgrounds to have the awareness of each issue jointly throughout the fundamental ideas, methods and modeling presented.
