Outline of Final Research Achievements

The purpose of this research was to examine the method used in the Jacobi analysis and to extend it to multivariate analysis, especially on semisimple Lie groups with higher rank. By rewriting the inverse Abel transform in terms of a Euclidean fractional differential operator, the relationship between the Jacobi analysis and the harmonic analysis on Euclidean space has been more clarified. This improves the singular integral theory on real rank-1 semisimple Lie groups. As for multi-variable cases, we investigated the case of SU(n,m) as an example, and obtained the end-point estimate of the Kunze-Stein phenomenon related to convolution operators. This was the first result for the higher rank case.

Academic Significance and Societal Importance of the Research Achievements

ユークリッド空間上の調和解析を半単純リー群上に拡張する研究は、調和解析の主分野となっている。フーリエ解析の類型までは完成しているが、一般の特異積分論となると実ランク1な半単純リー群およびその拡張であるヤコビ解析の場合を除くと、結果に乏しい。今回の逆アーベル変換をユークリッド空間の分数微分作用素で表す手法により、例ではあるがSU(n,m)(ランクn) の場合に結果が得られたことは意義がある。とくに上記手法の有効性を確かめることができた。計算にはSU(n,m)の具体的な構造を用いているので、今後はこの性質を一般の高ランクな半単純リー群に拡張したい。
