Research Abstract

1。熊谷は、半平面上の優臨界確率パーコレーションクラスターを典型例とするような、ある種の境界付き領域上のランダム媒質に対して、その上のランダムウォークのquenched invariance principleを証明した。(Z.-Q. Chen氏、D.A. Croydon氏との共同研究、論文は雑誌に投稿中。)
2。重川はマルコフ半群の p乗可積分な空間における収束性を調べ、半群の超縮小性の仮定の下で、収束の指数オーダーがpに依らないことを示した。また実際にpに依存する例を構成し、スペクトルを完全に決定することに依ってpへの依存性を示した。
3。相川は、除外集合を許したHarnback連鎖に対するHarnack不等式を示した、Intrinsic Ultracontractivityを容量的幅とGreen関数により導いた。
4。木上は、距離・測度空間の tree による parametrization の定義を与え、距離が parametrization と compatibleであるための条件、2つの距離が互いにquasisymmetric になるための必要十分条件、測度が距離に対してvolume doubling になるための必要十分条件などを考察した。
5。日野はフラクタル集合上の局所ディリクレ形式に付随する非自明な内在的距離を考察し,幾何学的な測地距離との関係について研究した。
