摘要
提出了r不定序同态、r连续序同态、r开序同态并讨论了它们之间的相互关系,得出了LF-r开集在开子空间中仍是LF-r开集,两个LF拓扑空间之间序同态r连续的充要条件等结论。
The present paper proposed indefinite homomorphism, continuous homomorphism, open homomorphism and discussed the relationships among them. A theorem says LF- open set is still LF- open set in open subspace is proved, and the sufficient and necessary condition for homomorphism between two LF topological space being -continuous is obtained.
