| 单词 | Obstruction |
| 释义 | ObstructionObstruction theory studies the extentability of Maps using algebraic Gadgets. While theterminology rapidly becomes technical and convoluted (as Iyanaga and Kawada note, ``It is extremely difficult to discusshigher obstructions in general since they involve many complexities''), the ideas associated with obstructions are veryimportant in modern Algebraic Topology.
