Research Abstract

本研究課題の研究の過程で, 写像の共形性を調べる必要があり, その研究を進めた. リーマン多様体(M.g)からリーマン多様体(N,h)へのなめらかな写像 f に対して, テンソルT_f=f^*h-1/m|df|^2gのノルムの二乗の積分で定義される汎関数を調べた. ここで, f^*hはfによるpull-back metric で, mはリーマン多様体(M,g)の次元である.第1 変分公式,第2変分公式,monotonicity formulaタイプの評価式(この場合,monotonenon-decreasing にはならない), Bochner formulaタイプの評価式などが得られた. 現在も, 研究を進めている.
