Outline of Annual Research Achievements

テンソル対称性を持つ独立同分布行列間の大域的関係に関する研究をドイツ・ハイデルベルク大学のRazvan Gurau氏およびフランス・リヨン高等師範学校のLuca Lionni氏と行った。ランダム行列理論で知られているモーメント理論、R変換、不変量の漸近挙動といった結果をテンソルのレベルまで高めたもので、量子情報理論への応用についても研究を行った。特に、大規模量子系のエンタングルメントを検出するためのテンソルHCIZ積分を研究し、共著論文「The tensor Harish-Chandra-Itzykson-Zuber integral II: detecting entanglement in large quantum systems」にまとめ投稿しComm. Math. Phys.に掲載された。また、米国のシラキュース大学のPierre Yves Gaudreau Lamarre氏、フランス・ボルドー大学のCamille Male氏と不変状態に対するテンソル積空間におけるユニタリ行列の漸近的自由性が示し、論文「Asymptotic freeness of unitary matrices in tensor product spaces for invariant states」としてまとめRandom Matrices Theory Appl. に掲載された。ルクセンブルク大学のWangjun Yuan氏および中国の香港中文大学のJeff Yao氏と、組合せ的手法を用いたテンソルを持つランダム行列の新しい研究をした。その後、Wangjun氏との共同研究でBandeira・Boedihardjo・van Handel氏らの半円要素とガウス変数の補間の手法を応用され、強漸近的自由性を証明しようとしている。部分的な成果は得られており、その完成を目指している。
