摘要

证明了第二可数空间T0 X上的Tang-Pequignot可约性(或相对连续关系的可约性)与给定拓扑的Wadge可约性相一致，或者X上不存在可以使其变为Wadge可约性的拓扑。

Continuous reducibility: functions versus relations

It is proved that the Tang-Pequignot reducibility (or reducibility by relatively continuous relations) on a second countable, T0 space X either coincides with the Wadge reducibility for the given topology, or there is no topology on X that can turn it into Wadge reducibility.
