On the relation between lifting obstructions and ordinary obstructions
摘要：
我们考虑部分提升的地图纤维化和比较的主要障碍，以延长提升与障碍，延长提升作为一个简单的映入全空间。当纤维是一个Eilenberg-MacLane空间时，证明了这两个障碍之间的关系。此外，它表明，这一结果专门为众所周知的事实二次障碍。
英文摘要：
We consider partial liftings of maps at fibrations and compare the primary obstruction to extend the lifting with the obstruction to extend the lifting as a simple map into the total space. A relation between these two obstructions is proved for the case when the fiber is an Eilenberg-MacLane space. Furthermore it is shown that this result specialises to well known facts about secondary obstructions.
