Semi-algebraic partition and basis of Borel-Moore homology of hyperplane arrangements
Published 10 Feb 2011 in math.GT, math.AG, and math.CO | (1102.2039v2)
Abstract: We 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. We also give an explicit correspondence between the de Rham cohomology and the Borel-Moore homology.
