分次原子格层同调的删除限制
Deletion-restriction for sheaf homology of graded atomic lattices
摘要：
利用消去格和限制格，给出了具有模模层的分次原子格的同调的长正合序列。然后，这是用来计算的配置格的超平面安排配备了自然层的同源性。这概括了Lusztig的一个旧结果。
英文摘要：
We give a long exact sequence for the homology of a graded atomic lattice equipped with a sheaf of modules, in terms of the deleted and restricted lattices. This is then used to compute the homology of the arrangement lattice of a hyperplane arrangement equipped with the natural sheaf. This generalises an old result of Lusztig.
