有限集的排列构成的格

Lattices of All Arrangements in Finite Sets

采用文献[1]中研究子空间轨道生成格的方法,对有限集合的所有排列作成的格进行了深入的研究,给出这种格之间的包含关系、格中元素的刻画及其特征多项式.

With the method of studying lattices generated by orbits of subspaces,lattices of all arrangements in finitesets are given in[1].A deep research to relations between the lattices,depiction of the elements in them and characteristic popynomial of the lattices are provided.
