## Models for real subspace arrangements and stratified manifolds.(English)Zbl 1068.32020

Consider a central plane arrangement in a vector space and let $$M$$ denote its complement. In the first part of the paper, the author constructs certain compactifications of $$M/\mathbb{R}^+$$ by embedding it in products of spheres. He shows that these compactifications are manifolds with corners and describes their boundaries. In the second part of the paper, the author describes a generalization of the previous procedure in terms of a sequence of blowups of stratified manifolds along strata.
This part of the paper is a real version of a procedure described in [R. MacPherson and C. Procesi, Sel. Math., New Ser. 4, No. 1, 125–139 (1998; Zbl 0934.32014)].
