本文利用任意n维平直空间(平移群流形)到n维球Sn的Kronccker映象,给出平移群的任意高阶同调群上闭链的明显表达式。映象的拖回可作物理解释。An explicit expression for any higher cocycles in translation group is given by means of Kronecker mapping from the n-dimensional flat space (translation group manifold) to the n-dimensional sphere. Physical interpretations can be made about the pull-back of the map.
