摘    要:引入了基-中紧映射,并证明了如下结果:①设f:X→Y是闭Lindelff映射,若X为正则空间,则f:X→Y是基-中紧映射;②若X和Y都为基-可数中紧的,Y为局部紧的,则X×Y为基-可数中紧的.

关 键 词:闭Lindelff映射  基-中紧映射  基-可数中紧

Abstract:The notion of base-mesocompact mapping is introduced and the following results are proved:①Let f:X→Y be a closed Lindeloff mapping.If X is regular,then f:X→Y is base-countable mesocompact mapping;② Let X and Y be both base-mesocompact.X×Y is base-countable mesocompact if Y is locally compact.
Keywords:closed Lindelff mapping  base-mesocompact mapping  base-countable mesocompact
