Geometrically constructed bases for homology of non-crossing partition lattices
The electronic journal of combinatorics, Tome 16 (2009) no. 1
For any finite, real reflection group $W$, we construct a geometric basis for the homology of the corresponding non-crossing partition lattice. We relate this to the basis for the homology of the corresponding intersection lattice introduced by Björner and Wachs using a general construction of a generic affine hyperplane for the central hyperplane arrangement defined by $W$.
