QUESTION OF ESSENTIALLY EXTENDABLE HOMEOMORPHISM  

作　　者：刘立榆 

机构地区：[1]Department of Mathematics, Jiangxi University, Nanchang 330047, PRC Let P be a pseudo-arc in 2-sphere S~2. A homeomorphism h : P →→P is called essentially extendable iff there exists an imbedding φ:P →S~2 such that the homeomorphism φhφ~(-1): φ(P)→φ(P)can be extended to S~2.

摘　　要：Let P be a pseudo-arc in 2-sphere S². A homeomorphism h : P →→ P is called essentially extendable iff there exists an imbedding φ:P → S² such that the homeomorphism φ hφ^-1: φ（P）→φ（P）can be extended to S².
