多維複空間中緊緻集合多項式凸性的研究: 凱琳引理的一些應用

On polynomial convexity of compact sets in C^n: Some applications of Kallin's lemma

指導教授 : 程守慶

摘要


應用凱琳引理,討論多複變空間中緊緻集合的多項式凸性。如n維度複數空間中有限多個球、2維度複數空間中3個分離多圓盤、2維度複數空間中四面體之稜及n維度複數空間中的樹。

並列摘要


We discuss the polynomial convexity of compact sets in C^n by applying Kallin’s separation lemma. For example, finite number of balls in C^n, 3 disjoint polydiscs in C^2, edges of tetrahedron in C^2 and trees.
