Consider a central plane arrangement in a vector space and let denote its complement. In the first part of the paper, the author constructs certain compactifications of 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)].
