Outline of Final Research Achievements

In this project, we proved the boundary Schwarz lemma for holomorphic mappings between finite dimensional irreducible bounded symmetric domains or between complex Hilbert balls.
We extended several necessary and sufficient conditions to be Bloch functions for holomorphic functions on finite dimensional bounded symmetric domains to infinite dimensional bounded symmetric domains. As an application, we proved that bounded holomorphic functions are Bloch functions.
We proved the existence of bounded support points for the family of holomorphic mappings on 2-dimensional Euclidean unit ball which have g-parametric representation.

Academic Significance and Societal Importance of the Research Achievements

これまで得られていた境界シュワルツの補題を、より一般的な有限次元既約有界対称領域や無限次元ヒルベルト空間の単位球に対して証明した。また、境界における条件を連続微分可能性より弱い条件であるJulia-Wolff-Caratheodoryの定理のタイプの仮定の下に証明した。
ブロック関数・ブロックセミノルムの新しい定義を用いて、無限次元空間までブロック関数、ブロック空間の定義を拡張した。また、その応用として、有限次元のときに未解決であった(重み付)合成作用素に関する様々な問題を無限次元のときまで含めて解決した。
