Counterexamples to the Complement Problem

Algebraic Geometry 2017-02-13 v4

Abstract

We provide explicit counterexamples to the so-called Complement Problem in every dimension n3n\geq3, i.e. pairs of non-isomorphic irreducible hypersurfaces H1,H2CnH_1, H_2\subset\mathbb{C}^{n} whose complements CnH1\mathbb{C}^{n}\setminus H_1 and CnH2\mathbb{C}^{n}\setminus H_2 are isomorphic. Since we can arrange that one of the hypersurfaces is singular whereas the other is smooth, we also have counterexamples in the analytic setting.
