Outline of Final Research Achievements

In recent years, research has been conducted to elucidate portfolio optimization problems using statistical mechanical informatics that can overcome these difficulties, except but for portfolio optimization problems with multiple constraints. Not enough research has discussed the primal-dual structure, the mathematical structure of each optimal solution, and the relational expression between macro variables. Therefore, through this research, we compare the investment risk minimization problem (primal problem) and the expected return maximization problem (dual problem) using statistical mechanical informatics, and disclose their primal-dual structure and macroscopic theory.

Academic Significance and Societal Importance of the Research Achievements

ポートフォリオ最適化問題に対する情報統計力学の研究はこれまでにもいくつ か行われているが,投資システムを主双対構造の観点から正しく議論することにより,そこで得られた成果は実際の投資行動の最適な指針になる (投資家の期待に応える知見を提供できる ) と 予想される.さらに本研究により,情報統計力学を通してポートフォリオ最適化問題を他分野と関連付けることで,有機的で学際領域的な研究分野に発展することができた.
