摘要翻译:
我们确定了a型Springer纤维的Betti数。为了做到这一点,我们构造了Springer纤维的单元分解。细胞的余维数由Coxeter长度的类似物给出。这使得我们的单元分解很适合于Betti数的计算。

英文摘要:
We determine the Betti numbers of the Springer fibers in type A. To do this, we construct a cell decomposition of the Springer fibers. The codimension of the cells is given by an analogue of the Coxeter length. This makes our cell decomposition well suited for the calculation of Betti numbers.
