Outline of Annual Research Achievements

本年度はN=2 AD臨界点を体現するGWW型のUNITARY行列模型の臨界現象について著しい進展があった。double scaling limitを利用してsuscepibility
functionに対する exp(-number/kappa)の形の非摂動効果を明示し、また元の行列模型の分配関数からあらわに計算する方法及び具体計算に成功した。

Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

順調に進行していることに特に理由はない、必要ない。

Strategy for Future Research Activity

調書に書いた通り

Causes of Carryover

当該年度の最後の2か月は多忙であり台湾出張による研究協力がままならなかった。次年度前半に実施予定に繰り下げるので次年度使用の必要性が生じた。
