1(1~*)-次仿紧空间的次仿紧逆象(英文)
Subparacompact inverse i mages of1(1~*)-subparacompact spaces
【摘要】 证明了次仿紧映射逆保持1(1*)-次仿紧性;作为应用我们证明了闭Lindelof正则映射逆保持1(1*)-次仿紧性(不需要原象空间和原象空间是正则的).
【Abstract】 We prove that subparacompact mappings inversely preserve 1(1*)-subparacompactness.As an applicationof this result,we obtain closed Lindelof regular mappingsinversely preserve 1(1*)-subparacompactness(without re-quiring the regularity of the spaces involved).
