| Outline of Final Research Achievements |
Regarding pseudoconvexity and intermediate pseudoconvexity for complex manifolds or for complex spaces, there are still many problems that need to be solved. In this study, we obtained a characterization for unramified domains over the space of n-tuples of complex numbers using quadratic functions to satisfy the intermediate pseudoconvexity. In addition, we obtained some new results on the n-Rungeness for open sets in n-dimensional complex manifolds, on planar open Riemann surfaces, and on the K-envelopes of holomorphy of K-complete normal complex spaces.

| Academic Significance and Societal Importance of the Research Achievements |
この研究において得られたいくつかの成果，例えば，ｎ個の複素数の組全体のなす空間の上の不分岐領域が中間的擬凸性をみたすための新しい特徴付けについては，それがもっと一般的な状況における擬凸性・中間的擬凸性の考察のための応用の可能性をもつことなど，多変数関数論・複素解析幾何の今後の一定の発展のために寄与するためのいくつか緒であることが期待される．
