Outline of Final Research Achievements

Because a group is consisted by individuals, the decisions of individuals in the group affects the group dynamics. On the other hand, the behaviour of each individual is based on the group dynamics. Thus, the the interaction of group and its member has a complex behaviour. In this research. as the bases of our analysis, we take the stock market, eusocial insects who breed cooperatively, and the interaction of the demand and the huge service providers, we provide the analytical framework of the interaction and check its realty.

Academic Significance and Societal Importance of the Research Achievements

従来の研究における解析は、個体を確定的に微分方程式で記述したり、確率的な挙動をMarkov過程として記述することが多かった。一方、集団の解析はシミュレーションや流体による近似を行うのが主流であった。近年、集団と個体をダイレクトに記述する手法として、平均場近似ゲームやnon-linear Markov過程といった新しい数学的枠組みが提案されている。この研究では、これらの手法を応用することで、今まで知られていなかったシステムの挙動が明らかできることを検証した。
