Semi-algebraic partition and basis of Borel-Moore homology of hyperplane arrangements
The authors describe an explicit semi-algebraic partition for the complement of a real hyperplane arrangement such that each piece is contractible and so that the pieces form a basis of Borel-Moore homology. They also give an explicit correspondence between the de Rham cohomology and the Borel-Moore homology.
